Controller IC Chip - MOSFET RT8228BGQW RT8228B 44 chip for laptop- Integrated portable calculator chip(SKU.1-CHIP0977)

Single Synchronous Buck PWM Controller

The RT8228B 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 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 RT8228B 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 MOSFETs and enter diode emulation mode at light load condition. The buck conversion allows this device to directly step down high voltage batteries at the highest possible efficiency. The RT8228B is intended for CPU core, chipset, DRAM, or other low voltage supplies as low as 0.5V. The RT8228B is available in a WQFN-12L 2x2 package
