Product Details
The MAX756 is a step-up DC-DC switching regulator
with a selectable output of either +3.3V or +5V.
The MAX756 has a high switching frquency allowing for
smaller sized external components. The device also
offers a high efficiency of up to 87% with a very
low Quiescent current of just 60µA.
Features
- Operates Down to 0.7V Input Supply Voltage
- 87% Efficiency at 200mA
- 60µA Quiescent Current
- 20µA Shutdown Mode with Active Reference and LBI Detector
- 500kHz Maximum Switching Frequency
- ±1.5% Reference Tolerance Over Temperature
- Low-Battery Detector (LBI/LBO)
