Product Details
General Description
The MAX1945R/MAX1945S high-efficiency pulse-width modulation (PWM) switching regulators deliver up to 6A of output current. The devices operate from an input supply range of 2.6V to 5.5V and provide selectable output voltages of 1.8V, 2.5V, and adjustable output voltages from 0.8V to 85% of the supply voltage.
Features
♦ 6A PWM Step-Down Regulator with 95% Efficiency♦ 1MHz/500kHz Switching for Small External Components
♦ 0.76in2 Complete 6A Regulator Footprint
♦ External Components’ Height <3mm
♦ ±1% Output Accuracy over Load, Line, and Temperature
♦ Operate from 2.6V to 5.5V Supply
♦ Operate from 2.5V Input with VCC at 3.3V/5V
♦ Preset Output Voltage of 1.8V or 2.5V
♦ Adjustable Output from 0.8V to 85% of Input
♦ Voltage Margining: ±4% (MAX1945R) or ±9% (MAX1945S)
♦ Synchronize to External Clock
♦ SYNCOUT Provides 180-Degree Out-of-Phase Clock Output
♦ All-Ceramic or Electrolytic Capacitor Designs
