High Efficiency Boost LDO Converter & High Power White LED Driver
General Description
Features
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 externa...
