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
