MagnaChip Launches Low Noise, Low Power Consumption, Fast Transient LDO Regulator for BGA SSD Used in Mobile Devices
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."
