Description

The LTC®3251/LTC3251-1.2/LTC3251-1.5 are 2-phase charge pump step-down DC/DC converters that produce a regulated output from a 2.7V to 5.5V input. The parts use switched capacitor fractional conversion to achieve twice the typical efficiency of a linear regulator. No inductors are required. VOUT is resistor programmable from 0.9V to 1.6V or fixed at 1.2V or 1.5V, with up to 500mA of load current available.

A unique 2-phase spread spectrum architecture of LTC3251/LTC3251-1.2/LTC3251-1.5 provides a very low noise regulated output as well as low noise at the input.* The parts have four operating modes: Continuous Spread Spectrum, Spread Spectrum with Burst Mode operation, Super BurstTM mode operation and shutdown.

Low operating current (35mA in Burst Mode operation, 10mA in Super Burst mode operation) and low external parts count make the LTC3251/LTC3251-1.2/LTC3251-1.5 ideally suited for space-constrained battery-powered applications. The parts are short-circuit and overtemperature protected, and are available in a thermally enhanced 10-pin MSOP package.
