Description

The RT9264 is a compact, high efficient, step-up DC/DC converter with current mode PWM control loop, providing stable and high efficient operations without external compensation.

The RT9264 suitable for 1 to 4 battery cells as well as USB power applications providing up to 400mA output current. The high switching rate minimized the size of external components.

A 300mA LDO is included in RT9264 to provide a secondary low noise output as well as an output current stop in the shutdown mode. RT9264 is provided in SOP-8 packages.
