MAX744A Datasheet (Maxim) - Current-Mode PWM DC-DC Converters

MAX744A, Current-Mode PWM DC-DC Converters

The MAX730A/MAX738A/MAX744A are 5V-output CMOS, step-down switching regulators.

The MAX738A/ MAX744A accept inputs from 6V to 16V and deliver 750mA.

The MAX744A guarantees 500mA load capability for inputs above 6V and has tighter oscillator frequency limits for low-noise (radio) applications.
