微源深圳供应 LP6201 低噪声升压转化IC
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.
