LTC3221 Micropower, Regulated 5V or 3.3V Charge Pump in 2 x 2 DFN

Sep 12th 2016
The LTC3221 family are micropower charge pump DC/DC converters that produce a regulated output at up to 60mA. The input voltage range is 1.8V to 5.5V. Extremely low operating current (8μA typical at no load) and low external parts count (one flying capacitor and two small bypass capacitors at VIN and VOUT) make them ideally ...

LTC3245 High Efficiency 3.3V Microcontroller Supply from 9V Alkaline (with Power-On Reset Delay)

Sep 2nd 2016
The LTC3245 is a switched capacitor buck-boost DC/DC converter that produces a regulated output (3.3V, 5V or adjustable) from a 2.7V to 38V input. The device uses switched capacitor fractional conversion to maintain regulation over a wide range of input voltage. Internal circuitry automatically selects the conversion ratio to ...

Low Power 5V Battery Backup Supply with Autoswitchover and No Reverse Current

Jul 1st 1997
The LTC1514 is a micropower switched capacitor DC/DC converters that produce a regulated output voltage by either stepping up or stepping down the input voltage. Output voltage is fixed at either 3.3V or 5V by an internal resistor. An internal low-battery comparator is kept active in shutdown. ...
