资 源 简 介

The RT9278 is a compact, high efficiency, synchronousstep-up converter, it provides a power supply soluTIon forproducts 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 synchronousrecTIfier. The maximum peak current in the internal switchis limited to up to 2A.It keeps the output voltage regulated when the inputvoltage exceeds the setTIng output voltage. The outputvoltage can be set by an external resister divider, or befixed to reduce external components. It integrates a linearcontroller for linear regulator.RT9278 is available in VDFN-10L 3x3 package.
