Product Description

Description:
  • The RT8204A PWM controller provides the 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.
