LTC3200 Regulated 5V Output from a 2.7V to 4.5V Input

Sep 12th 2016
A new charge-pump architecture maintains constant switching frequency to zero load and reduces bith output and input ripple. The LTC3200/LTC3200-5 have thermal shutdown capability and can survive a continuous short-circuit from VOUT to GND. Built-in soft-start circuitry prevents excessive inrush curreent during start-up. ...

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 ...
