MAX1970 - Dual / 180 Out-of-Phase / 1.4MHz / 750mA Step- Down Regulator
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.
