Overview

19-2297; Rev 0; 1/02 Dual, 180° Out-of-Phase, 1.
4MHz, 750mA StepDown Regulator with POR and RSI/PFO General Description The MAX1970/MAX1971/MAX1972 dual-output currentmode PWM buck regulators operate from 2.
6V to 5.
5V input and deliver a minimum of 750mA on each output.
The MAX1970 and MAX1972 operate at a fixed 1.
4MHz (MAX1971 operates at 700kHz) to reduce output inductor and capacitor size and cost.
Switching the regulators 180° out-of-phase also reduces the input capacitor size and cost.
Ceramic capacitors can be used for input and output.
The output voltages are programmable from 1.
2V to VIN using external feedback resistors, or can be preset to 1.
8V or 3.
3V for output 1 and 1.
5V or 2.
5...
