The GS2250 is a 5A ultra low dropout linear regulator. The IC needs two supply voltages, one is a control voltage (VCNTL ) for the control circuitry, the other is a main supply voltage (VIN ) for power conversion, to reduce power dissipation and provide extremely low dropout voltage. The GS2250 integrates many functions. A Power‐On‐ Reset (POR) circuit monitors both supply voltages on VCNTL and VIN pins to prevent erroneous operations. The functions of thermal shutdown and current‐limit protect the device against thermal and current over‐loads.

SINGLE SYNCHRONOUS STEP SINGLE SYNCHRONOUS STEP‐ ‐DOWN CONTROLLER DOWN CONTROLLER

The constant‐on‐time PWM control scheme handles wide input/output voltage ratios with ease and provides 100ns “instant‐on” response to load transients while maintaining a relatively constant switching frequency. The GC31100 achieves high efficiency at a reduced cost by eliminating the current‐sense resistor found in traditional current‐mode PWMs. Efficiency is further enhanced by its ability to drive very large synchronous rectifier MOS‐FETs. The buck conversion allows this device to directly step down high‐voltage batteries for the highest possible efficiency. The GC31100 is intended for CPU core, chipset, DRAM, or other low‐voltage supplies as low as 0.75V. The GC31100 PWM controller provides high efficiency, excellent transient response, and high DC output accuracy needed for stepping down high‐voltage batteries to generate low‐voltage CPU core, I/O, and chipset RAM supplies in notebook computers.

The GC31101 is a cost effective, synchronous buck controller for POL voltage regulation in notebook PC applications. The controller is dedicated for Adaptive On‐Time D‐CAP™ Mode operation that provides ease of use, low external component count, and fast transient response. Auto‐skip mode for high efficiency down to the mA load range, or PWM‐only mode for low noise operation is selectable.

The current sensing scheme for positive over current and negative over current protection is loss‐less low‐side RDS(on) sensing plus temperature compensation. The conversion input can be either VBAT or 5‐V rail, ranging from 1.8 V to 28 V, and the output voltage range is from 0.75V to 5.5V
