3/LTC1751-5 Micropower, Regulated Charge Pump DC/DC Converters FEATURES s s s s s s s s s s s s s DESCRIPTIO 5V Output Current: 100mA (VIN ≥ 3V) 3.
3V Output Current: 80mA (VIN ≥ 2.
5V) Ultralow Power: 20µA Quiescent Current Regulated Output Voltage: 3.
3V ± 4%, 5V ± 4%, ADJ No Inductors Short-Circuit/Thermal Protection VIN Range: 2V to 5.
5V 800kHz Switching Frequency Very Low Shutdown Current: <2µA Shutdown Disconnects Load from VIN PowerGood/Undervoltage Output Adjustable Soft-Start Time Available in an 8-Pin MSOP Package The LTC®1751 family are micropower charge pump DC/ DC converters that produce a regulated output voltage at up to 100mA.
The input voltage range is 2V to 5.
5V.
Extremely low operating current (20µA typical with no load) and low external parts count (one flying capacitor and two small bypass capacitors at VIN and VOUT) make them ideally suited for small, battery-powered applications.
The LTC1751 family operate as Burst ModeTM switched capacitor vol...
