Product Information
Product Overview
The MAX757CSA+ is a CMOS step-up DC to DC converter in 8 pin NSOIC package. This DC to DC switching regulator is used for small, low input voltage or battery powered systems. The device is an adjustable version that accepts an input voltage down to 0.7V and generates a higher adjustable output voltage in the range from 2.7V to 5.5V. The device has reduced physical size and high switching frequencies up to 0.5MHz which is made possible by MOSFET power transistors that allows for tiny (<lt/>5mm diameter) surface mount magnetics. 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 unique constant off time pulse frequency modulation control scheme.
- Input voltage range from 700mV to 5.5V
- Operating temperature range from 0°C to 70°C
- Output current of 300mA
- 20μA shutdown quiescent current with active reference and low battery detector (LBI/LBO)
- ±1.5% reference tolerance over temperature
Applications
Power Management, Medical, Consumer Electronics, Portable Devices
