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.
