General Description

The RT9263 is a compact, high efficient, step-up DC/DC

converter with an adaptive current mode PWM control

loop, providing a stable and high efficient operation over

a wide range of load currents. It operates in both

continuous and discontinuous current modes in stable

waveforms without external compensation.
