MAX779LC/D规格书详情
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.
Features
♦ 1V to 4.5V Input Guarantees Start-Up Under Load
♦ Up to 210mA Output
♦ Load Fully Disconnected in Shutdown
♦ 82 Efficiency
♦ Output in Regulation with Input Voltage above Output Voltage
♦ Internal 1A Power Switch and Active Rectifier
♦ Adjustable Current Limit Allows Low-Cost Inductors
♦ 190µA No Load Supply Current
♦ 20µA Shutdown Supply Current
♦ 3V/3.3V (MAX778L), 5V (MAX777L), and Adjustable (MAX779L) Output Voltage
