Product Details
The MAX619 is a step-up dc-dc converter supplying a
steady 5V from an input voltage between 2V to 3.6V.
The MAX619 requires only 4 external capacitors and has a very small
pcb footprint. The device has a low operating current and very low
shutdown supply current, making the device ideal for small
battery operated applications.
Features
- Regulated 5V ±4% Charge Pump
- Output Current Guaranteed over Temperature
- 2V to 3.6V Input Range
- No Inductors: Very Low EMI Noise
- Ultra-Small Application Circuit
- Uses Small, Inexpensive Capacitors
- Logic-Controlled 1µA MAX Shutdown Supply Current
- Shutdown Disconnects Load from Input
