The RT8012A is a dual PWM, current mode, stepdown
converter. Its input voltage range is from 2.6V to 5.5V and
has a constant 1.2MHz switching frequency, allowing the
use of tiny, low cost capacitors and inductors 2mm or
less in height. Each output voltage is adjustable from 0.8V
to 5V. Internal power switches with low on-resistance of
the dual step-down regulators increase efficiency and
eliminate the need for external Schottky diodes. The
RT8012A can run at 100% duty cycle for low dropout
operation that extends battery life in portable systems.
With independent Enable and Power-Good pins, it is easy
to control the power up sequence of the two converters,
which is important in some applications.
