5-Bit Programmable Synchronous PWM

Buck Converter Controller

General Description

The RT9223 is a high efficiency synchronous

switching regulator for modern CPU application. The

output is controlled by a 5-bit DAC programmed from

1.3V to 2.05V in 0.05V steps and from 2.1V to 3.5V

in 0.1V increments.

The switching controller drivers two N-MOSFETs at

200KHz frequency and provides an optimal solution

for size, efficiency and cost in any application

circuits. The controller also offers integrated

functions including PGOOD, output enable, over-

voltage, internal digital-count soft start, and current-

limiting protection in one chip.
