MAX779L Datasheet Low-voltage Input / 3v/3.3v/5v/ Adjustable Output / Step-up DC-dc Converters

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-0186; Rev 2; 7/96 NUAL KIT MA ATION U EET L H A S V E TA WS DA FOLLO Low-Voltage Input, 3V/3.

General Description

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 of 3.0V or 3.3V, and the MAX779L output can be adjusted from 2.5V to 6V through an external resistive divider.

Key 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 Load Supply Current o 20µA Shutdown Supply Current o 3V/3.3V (MAX778L), 5V (MAX777L), and Adjustable (MAX779L) Output Voltage _______________General.
