SEOUL, South Korea, March 15, 2021 — Magnachip Semiconductor Corporation (“Magnachip”) (NYSE: MX) announced today that the company has released a new Low-dropout (LDO) linear regulator featuring an ultra-fast transient response for a Universal Flash Storage (UFS)-based Multi-Chip Package (MCP).

UFS is an advanced version of an Embedded Multi-Media Controller (eMMC), which was developed for concurrent read and write performance at higher speeds. UFS-based MCP is a memory module that integrates UFS controller and memory ICs, such as DRAM or NAND flash. It is mainly used for the storage function in smartphones.

Magnachip’s LDO linear regulator is designed for the power supply of NAND flash in UFS-based MCP with an input voltage of up to 500mA. It reduces input noise with its power supply rejection ratio function, while providing a low-leakage current of 75uA in deep sleep mode, which will enhance battery life and power efficiency.

A key feature of this new product is ultra-fast transient response, minimizing output-voltage fluctuations. Frequent changes in voltage normally occur in UFS-based MCPs due to varying levels of read and write performance. However, ultra-fast transient response regulates these fluctuations to a steady state within 100 nanoseconds.

The line regulation and load regulation in UFS-based MCP is maintained at 0.2% and 0.5% respectively, which will guarantee stable power supply. In addition, the dropout voltage is as low as 0.3V, which makes the linear regulator perfect for low-power domain operations of batteries.

This linear regulator also ensures robust circuit protection, such as overcurrent protection, thermal shutdown and the power good signal, which indicates that all of the output voltages are within specification.

“The demand for advanced power ICs is growing as electronic devices become more sophisticated and have increasingly stringent requirements for stable and efficient power supply,” said YJ Kim, CEO of Magnachip. “We will continuously expand our Power IC portfolio by delivering premium products for a wide range of data storage applications.”

Low-Rss(on) LV MOSFET for Battery Protection Circuit Modules

SEOUL, South Korea and SAN JOSE, Calif., June 26, 2019 /PRNewswire/ — MagnaChip Semiconductor Corporation (“MagnaChip” or the “Company”) (NYSE: MX), a designer and manufacturer of analog and mixed-signal semiconductor products, announced today a new low-Rss(on)* LV (Low Voltage) MOSFET with reduced chip size for smartphone battery PCMs (Protection Circuit Modules).

Extended life and increased protection for batteries in high-end LTE and 5G smartphones are becoming increasingly important. 5G phones, in particular, need longer-lasting batteries with higher endurance than previous smartphones to process the massive amount of data with extremely fast download and upload capabilities. Inserted in the battery PCMs in LTE or 5G phones, this newly released MOSFET prevents over-voltage and over-current of the batteries and ultimately helps extend their life and resolve the overheating issue.

The Rss(on) of this new product, 20 percent lower than previous versions with the same chip size, prolongs the life of smartphone batteries by decreasing current loss and improving heat dissipation. This lower Rss(on) also enables higher-power density than previous versions to prevent over-heating of the battery during a quick charge (a feature supported by most of the latest smartphones). PCM functionality is also enhanced by an ESD (Electrostatic Discharge) protection diode added to the product. This diode mitigates ESDs of ≤ 2 kV to strengthen circuit protection and prevents damage to other smartphone components.

MagnaChip also has reduced the chip size of this new MOSFET by 10 percent (as compared to other LV MOSFETs currently on the MagnaChip portfolio), which offers greater design flexibility for circuit designers and even shrinks the PCM itself. With this reduction in size, WLCSP (Wafer Level Chip Scale Package) is possible for this product.

“Quick charging, fast processor speeds and other advanced specifications for new LTE and 5G smartphones require power products that provide superlatively high levels of battery protection,” said YJ Kim, CEO of MagnaChip. “We are working closely with the OEM community to decrease the footprint of our MOSFETs and incorporate other product enhancements to meet these objectives.”

SEOUL, South Korea and SAN JOSE, Calif., June 4, 2019 — MagnaChip Semiconductor Corporation (“MagnaChip” or the “Company”) (NYSE: MX), a designer and manufacturer of analog and mixed-signal semiconductor products, announced today it has launched 3-channel BLU (backlight unit) LED driver for UHD TVs.

For high-resolution UHD displays, this new standard display product is designed to control the local LED dimming of up to 270 LEDs through a maximum of 90 LEDs per channel. In addition, it provides a dual dimming solution with Analog and PWM (Pulse Width Modulation) for efficient and stable LED dimming, which reduces power consumption and helps achieve a high contrast ratio in UHD TVs.

Analog dimming, a type of LED dimming technology, adjusts the brightness of the LED by controlling the amount of current flowing through the LED in a linear manner. With this solution, the LED color changes when the current fluctuates. By contrast, PWM dimming is a method to minimize the color change. MagnaChip’s new 3-channel BLU LED Driver is designed to selectively use analog or PWM dimming according to the image signal, thus providing the solution to realize high contrast ratio and power efficiency.

The BLU LED driver also provides for high current accuracy within ±1% tolerance by using the average mode of the current control technology. In addition, this product supports Low PWM Dimming by operating at 480 kHz High speed Switching Frequency to elaborately control the current in the dark area of the image with a narrow pulse width.

Other advantages of MagnaChip’s BLU LED driver are that it provides various circuit protection functions, including short-circuit protection and under-voltage lockout (UVLO) to attain high reliability. In addition, this product features over-duty protection, which keeps the PWM duty ratio (on/off ratio) constant. It also provides for current-sense resistor short protection, which prevents over-current from flowing into a specific area of the circuit. MOSFET drain-source short protection also detects and protects the shorts of the MOSFETs in the circuit.

YJ Kim CEO of MagnaChip said, “MagnaChip’s 3-channel BLU LED driver, which features low power and high contrast ratio, will enhance the product value of high definition UHD TV.” He added, “As the UHD TV market grows rapidly, we will continue to strengthen our display driver lineup by developing multi-channel BLU LED drivers that increase the number of channels as well as LED current accuracy.”
