产品概述
The MAX757CPA+ is a CMOS Step-up DC-DC Switching Regulator for small, low input voltage or battery-powered systems. The MAX757 is an adjustable version that accepts an input voltage down to 0.7V and generates a higher adjustable output voltage in the range from 2.7 to 5.5V. Typical full-load efficiencies for the MAX757 is greater than 87%. The MAX757 provide three improvements over previous devices. Physical size is reduced-the high switching frequencies (up to 0.5MHz) made possible by MOSFET power transistors allow for tiny (<lt/>5mm diameter) surface-mount magnetic. Efficiency is improved to 87% (10% better than with low-voltage regulators fabricated in bipolar technology). Supply current is reduced to 60µA by CMOS construction and an unique constant-off-time pulse-frequency modulation control scheme.
- Operates down to 0.7V input supply voltage

- 60µA Quiescent current
- 20µA Shutdown mode with active reference and LBI detector
- ±1.5% Reference tolerance over-temperature
- Low-battery detector (LBI/LBO)
