MAX756
Overview
The MAX756/MAX757 are CMOS step-up DC-DC switching regulators for small, low input voltage or battery-powered systems. The MAX756 accepts a positive input voltage down to 0.7V and converts it to a higher pinselectable output voltage of 3.3V or 5V.
- 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)
- 8-Pin DIP and SO Packages
