Description

The MCP1252-33X50 is an inductorless, positive regulating, low noise charge pump DC-to-DC converter. It has selectable outputs of either 3.3V or 5.0V and can deliver 120mA of load current at the selected regulated output voltage. Since the device incorporates an automatic buck/boost feature, it will maintain the regulated output voltage whether the input voltage is above or below the output voltage. The MCP1252 operates at a switching frequency of 650kHz and features a power-good pin that monitors out-of-regulation conditions.
