MAX744A Datasheet Current-mode Pwm DC-dc Converters

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-0165; Rev 2; 1/96 MAX730A/MAX738A/MAX744A 5V, Step-Down, Current-Mode PWM DC-DC Converters.

General Description

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.

Key Features
