RT8036
One Step Down DC/DC Converter and Four Linear
Regulators with Individual On/Off Control
General Description
The RT8036 is an integrated power management unit which
integrates one 600mA high efficiency step down DC/DC
converter and four low dropout voltage regulators with
300mA current capability for each regulator.
The RT8036 is optimized for sub block power requirement
solution. The individual on/off control for each device can
provide flexibility for different power on sequence. Four
linear regulators provide high PSRR output and are suitable
for both analog and digital power.
The RT8036 is available in the WQFN-20L 3x3 package
that is suitable for portable device.
