RT6543A/B
High Efficiency Single Synchronous Buck PWM Controller for INTEL VCCIN AUX ICL and TGL
General Description
The RT6543A/B PWM controller provides high efficiency, excellent transient response, and high DC output accuracy for stepping down high
voltage batteries to generate low
voltage CPU core, I/O, and chipset RAM.
The RT6543A/B supports on chip
voltage programming function between 0V and 1.
8V by controlling VID1/VID0 inputs.
Compared with conventional current-mode PWMs, the RT6543A/B achieves high efficiency without any current sensing resistors.
Furthermore, the RT6543A/B has ability to drive synchronous rectifier
MOSFETs and enters diode emulation mode at light load conditio...
