RT8240C - High Efficiency Single Synchronous Buck PWM Controller

Download the RT8240C datasheet PDF. This datasheet also covers the RT8240A variant, as both devices belong to the same high efficiency single synchronous buck pwm controller family and are provided as variant models within a single manufacturer datasheet.

Key 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.

® 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.
