Overview
® RT8240A/B/C High Efficiency Single Synchronous Buck PWM Controller General Description Features The RT8240A/B/C 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 RT8240A/B/C supports on chip voltage programming function between 1V and 1.
05V by controlling G0 digital inputs.
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 RT8240A/B/C ach...
