MAX8677AETG - Brand New Maxim Integrated Battery Management ICs
-
Description
The MAX8677AETG is an ultra-small, high-efficiency, CMOS, step-up, DC-DC switching regulator designed for 1-cell battery-powered systems. It accepts a positive input voltage between 0.8V and VOUT and converts it to a higher, pin-selectable output voltage of 3.3V or 5V. The MAX8677AETG has an adjustable version that accepts input voltages from 0.8V to 6.0V and generates a higher adjustable output voltage in the 2.7V to 6.0V range. With typical efficiencies greater than 80% and a low no-load supply current of 100µA, the MAX8677AETG provides maximum battery life. It also features a shutdown mode with a current draw of only 1µA and a high switching frequency that allows for the use of small, low-cost inductors and capacitors. The internal peak-current limiting protects the IC.
