... LIGHT LOAD, PFM MODE During light load conditions, the MCP1602 operates in a PFM mode. When the MCP1602 enters this mode, it begins to skip pulses to minimize unnecessary quiescent current draw by reducing the number of switching cycles per second. The typical quiescent current draw for this device is 45 µA. ...

... Soft Start The output of the MCP1602 is controlled during start- up. This control allows for a very minimal amount of V overshoot during start-up from V OUT the UVLO voltage or SHDN being enabled. 4.5 Overtemperature Protection Overtemperature protection circuitry is integrated in the MCP1602. This circuitry monitors the device junction ...

... NiMH batteries into a well regulated 1.5V @ 500 mA output. A 4.7 µF input and output capacitor, a 4.7 µH inductor, and a small RC filter make up the entire external component selection for this application. No external voltage divider or compensation is necessary. In addition to the fixed 1.5V option, the MCP1602 is also available in 1.2V, 1.8V, 2.5V, or 3.3V fixed voltage options. 5.3 Adjustable Output Voltage ...
