RT9224E Datasheet (Richtek Technology) - VRM 8.5 Synchronous PWM Buck Converter Controller and Output Voltage Monitor

RT9224E, VRM 8.5 Synchronous PWM Buck Converter Controller and Output Voltage Monitor

The RT9224E is a high speed switching controller designed for use in Synchronous DC/DC buck converter for modern CPUs.

The regulated output voltage is digitally programmable from 1.05V to 1.825V by a 5-bit DAC which provides initial accuracy of ±1%.

The RT9224E drives two external N-Channel MOSFETs,
