www.DataSheet4U.com M62203FP 3.3 V, 2.7 V Two-Channel Fixed-Output General-Purpose DC-DC Converter REJ03F0094-0100Z Rev.1.0 Sep.19.2003 Description The M62203FP is an integrated circuit developed as a two-channel (3.3 V and 2.7 V) fixed-output general-purpose DCDC converter. Peripheral elements are incorporated in a small 8-pin package, enabling peripheral circuitry to be simplified, and compact, low-cost set design to be achieved. In addition, the M62203FP has an on-chip reset circuit that monitors power supply voltage VCC (5 V) and output voltage Vout (3.3 V), enabling erroneous system operation to be prevented. Features Wide operating power supply voltage range: 4 to 15 V (5 V Typ.) Low current dissipation: 1.0 mA (VCC = 5 V, no load) On-chip 5 V, 3.3 V dual voltage system detection reset circuitry On-chip oscillation circuit not requiring peripheral elements (110 kHz Typ.) 8-pin SOP package Applications General electronic products such as mobile and portable devices Pin Configuration (Top View) Cout1 GND Cout2 Vcc 1 2 3 4 8 7 6 5 IN1 RESET Cd IN2 Package: 8P2S-A M62203FP Rev.1.0, Sep.19.2003, page 1 of 11 M62203FP Block Diagram Vcc 4 Cd 6 IN1; 3.3V 25 µ A Reference voltage 1.25V 7 RESET comp.
