RCR2562
PFM Step-up DC/DC Converter
z Features
• 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 = 3.3V )
• Ultra Low Input Current ( 12μA at Switch Off )
• ±2% High Output Voltage Accuracy
• Low Ripple and Low Noise
• 75% Efficiency with Low Cost Inductor
• SOT23-5L Small Packages
z General Description
The RCR2562 Series are PFM Step-up DC/DC ICs with ultra
low supply current by CMOS process and suitable for use with
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
z Applications
• Battery-powered equipment
• Cameras, Camcorders, VCRs, PDAs, pagers, electronic
data banks, and hand-held communication equipment
