RT6542A Overview
The RT6542A 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 puters. The RT6542A supports on chip voltage programming function between 0.85V and 1.05V by controlling GX digital inputs. The constant-on-time PWM control scheme handles wide...
