RCR2562 PFM Step-up DC/DC Converter
z Features
battery-powered instruments. Consists of an oscillator, a PFM control circuit, a driver Pin EXT to external MOSFET, a reference voltage unit, an error amplifier. A low ripple and high efficiency step-up DC/DC converter can be constructed of this RCR2562 IC with only six external components. The RCR2562 works on ultra low start-up voltage, typically max start-up voltage less than 1.1V at 1mA load current • Low Start-up Voltage, 1.1V at 1mA • Minimal Number of External Components ( Only an Inductor, a Diode, a MOSFET and two Capacitors ) •Adjustable version ( VREF = 1.25V VREF = 2.7V or VREF = 3.
