RCR2562

www.DataSheet4U.com ® 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 = 3.3V ) 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 Applications Battery-powered equipment z General Description Cameras, Camcorders, VCRs, PDAs, pagers, electronic data banks, and hand-held communication equipment The RCR2562 Series are PFM Step-up DC/DC ICs with ultra low supply current by CMOS process and suitable for use with z Package Information ③ ② ① ④ ⑤ Units:mm 1 /7 ISPD-V3.1 www.DataSheet4U.com ® RCR2562 z Pin Configurations Pin Port ① ② ③ ④ ⑤ SOT23-5L FB VIN NC GND EXT z Functional Block Diagram z Ordering Information RCR2562 - □□□ □□ Package Type SK: SOT23-5L Reference Voltage 125= 1.25V; 270= 2.70V; 330= 3.30V Indicate The Product Number z Absol...
