Where to use MCP16252
The MCP16252 is a synchronous step-up DC-DC converter IC, which is normally used in One, Two and Three-Cell Alkaline and NiMH/NiCd Portable Products. Since the regulation occurs through switching it is very efficient than linear circuits. The internal oscillator supports the switching frequencies from 425 kHz to 575 kHz.
The input voltage for the IC is from 0.82V to 5.5V and the output voltage can be varied from 1.8V to 5.5V and the maximum output current can be up to 100mA. So if you looking to design a DC-DC converter with the above specifications then MCP16252 might be of interest to you.
How to use MCP16252
This IC requires a minimum number of components to be operational. A test circuit diagram from the MCP16252 datasheet is given below. As shown in the circuit diagram output voltage is set by a small external resistor divider. VIN pin is connected to the input voltage source. The input source should be decoupled to GND with a 4.7 µF minimum capacitor. The VFB pin is used to provide output voltage regulation by using a resistor divider
