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) 1 GND 2 Cout2 3 Vcc 4 M62203FP Cout1 Package: 8P2S-A Rev.1.0, Sep.19.2003, page 1 of 11 8 IN1 7 RESET 6 Cd 5 IN2 M62203FP Block Diagram Vcc 4 Cd 6 IN1; 3.3V 25µA Reference voltage 1.25V 7 RESET comp. comp.
