SC46166

300mA ,500KHZ HIGH EFFICIENCY STEP-UP DC/DC CONVERTER

SOT-89-5

SOT-23-6

DESCRIPTION

The SC46166 is a compact, high efficiency, and low voltage

step-up DC/DC converter, includes an error amplifier, ramp

generator, current comparator, slope compensation, current sense

and driver. Peak current mode PWM control with internal

compensation reduces external parts count and provides a stable

and high efficient operation over a wide range of load currents.

The low start-up input voltage below 0.85V makes SC46166

suitable for 1 to 4 battery cells applications. A high switching

frequency of 500kHz minimizes overall solution footprint by allowing

the use of tiny, low profile inductors and ceramic capacitors. The

SC46166 shifts automatically to Power Saving Mode operation at

light loads, the 20uA low quiescent current together with high

efficiency maintains long battery lifetime. The device also features

low shutdown current of under 1

μA.
