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
