SEOUL, South Korea and SAN JOSE, Calif., Dec. 17, 2018 /PRNewswire/ -- MagnaChip Semiconductor Corporation ("MagnaChip") (NYSE: MX), a designer and
manufacturer of analog and mixed-signal semiconductor platform solutions, today announced that it has released a low noise, low
power consumption, fast transient LDO (Low Dropout) regulator that also can be designed into BGA (Ball Grid Array) SSD
(Solid State Drive) components commonly used in mobile devices. An LDO regulator is a power standard product whose function
can be designed into various components.
An LDO regulator is a DC voltage
regulator that can regulate an output voltage even when the supply voltage is immensely close to the output
voltage. The advantages of a LDO regulator over other DC-to-DC regulators include the absence of switching noise, smaller
device size, and greater design simplicity.
A BGA SSD refers to an SSD that integrates an SSD controller and a memory chip, such as DRAM and NAND flash, into a Ball
Grid Array package. It is about 60 percent smaller than a non-BGA SSD in size and, therefore, mainly used in mobile devices such
as notebook PCs, tablets PCs and smartphones.
The new product is developed especially for the stringent requirements of a BGA SSD power supply and provides a
stable 1.2V output voltage in the 1.65V to 3.3V input voltage range. It also is capable of supplying a maximum current of 500mA
and, by virtue of a high Power Supply Rejection Ratio (PSRR), it can remove input power noise. In addition, the product
realizes a low quiescent current of 75uA, which increases the power efficiency of mobile devices and extends battery
life.
By design, a BGA SSD has a high variation in its read / write load, which requires a stable power supply. To meet this
requirement, the new LDO regulator features an industry leading 0.5% fast transient response. MagnaChip also promotes
greater product safety by building in protection against current surges above rated specifications and enhanced power monitoring
features.
"We are pleased to launch our new LDO regulator with low noise, low power consumption and fast transient response." said YJ
Kim, CEO of MagnaChip. "We have a diversified portfolio of power standard products which includes power IC and discretes for
mobile, consumer electronics and industrial applications. The introduction of this LDO regulator will further expand our power IC
standard product portfolio for mobile devices."
