Low Noise PFM DC/DC Regulator

General Description

The LP6201 Series are PFM Step-up DC/DC ICs with ultra

low supply current by CMOS process and suitable for use

with battery-powered instruments. The LP6201 IC consists

of an oscillator, a PFM control circuit, a driver transistor

(LX switch), a reference voltage unit, an error amplifier,

resistors for voltage detection, and a LX switch protection

circuit. A low ripple and high efficiency step-up DC/DC

converter can be constructed of this LP6201 IC with only

three external components.
