Description
The MIC2660 IttyBitty™ charge pump functions as a lowcurrent, step-up converter where conventional inductor based, dc-to-dc converters are too complex and expensive.
Features
- a complete, self-contained charge pump in a tiny 5-lead SOT-23-5 package. The MIC2660 is powered from a 3V to 5V nominal supply and produces nominally 5V to 9V as a function of the input voltage. The output is unregulated and follows a load-line type function. The MIC2660 can be used with or without external components. When used with two noncritical external capacitors, a 3V input will produce 5V at 3.8mA. With no external components, a 3V input will produce 5V at 2.5mA. The MIC2660 charge pump.
