The RT9278 is a compact, high efficiency, synchronous
step-up converter, it provides a power supply solution for
products powered by either two-cell, three-cell Alkaline/
NiMH or one-cell Li-Ion/Li-polymer battery.
The RT9278 is boost converter with PWM control loop,
provide up to 95% efficiency by using a synchronous
rectifier. The maximum peak current in the internal switch
is limited to up to 2A.
It keeps the output voltage regulated when the input
voltage exceeds the setting output voltage. The output
voltage can be set by an external resister divider, or be
fixed to reduce external components. It integrates a linear
controller for linear regulator.
RT9278 is available in VDFN-10L 3x3 package.
