MAX8670AETL+ - Brand New Maxim Integrated IC Chips
-
Description
The MAX8670AETL+ 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 MAX8670AETL+ is also available in an adjustable version that accepts an input voltage between 0.8V and 6.0V, generating a higher adjustable output voltage in the range of 2.7V to 6.0V. This regulator offers typical efficiencies greater than 80% and has a low no-load supply current of 100µA (1µA in shutdown mode). In addition, it features ultra-low quiescent supply current, high efficiency, and internal peak-current limiting for better battery life. The high switching frequency allows for the use of small, low-cost inductors and capacitors. It is available in an ultra-small 8-pin µMAX package.
