Description:

(max877l - max879l) step-up & down dc-dc converters.

MAX879L, (MAX877L - MAX879L) Step-Up & Down DC-DC Converters

The MAX777L/MAX778L/MAX779L are pulse-skipping DC-DC converters that step up from low-voltage inputs (1V guaranteed).

They require only three external components *an inductor (typically 22µH) and two capacitors.

The MAX777L delivers a 5V output, the MAX778L generates pin-selectable voltages o

MAX879L Features

* o 1V to 4.5V Input Guarantees Start-Up Under Load o Up to 210mA Output o Load Fully Disconnected in Shutdown o 82% Efficiency o Output in Regulation with Input Voltage above Output Voltage o Internal 1A Power Switch and Active Rectifier o Adjustable Current Limit Allows Low-Cost Inductors o 190µA No
