RT9232 - Richtek

RT9232 Programmable Frequency Synchronous Buck PWM Controller

The RT9232 is a single-phase synchronous buck PWM DC-DC converter controller designed to drive two N-Channel MOSFET. It provides a highly accurate, programmable output voltage precisely regulated to low voltage requirement with an internal 0.8V ± 1% reference. The RT9232 uses an external compensated, single feedback loop voltage mode PWM control for fast tra.
