ADUM4070 - Isolated Switching Regulator

General Description

The ADuM40701 is a regulated dc-to-dc isolated power supply controller with an internal MOSFET driver.

The dc-to-dc controller has internal isolated PWM feedback from the secondary side based on the iCoupler® chip scale transformer technology and complete loop compensation.

Key Features

  • Isolated PWM feedback with built-in compensation Primary side transformer driver for up to 2.5 W output power with 5 V input voltage Regulated adjustable output: 3.3 V to 24 V Up to 70% efficiency 200 kHz to 1 MHz adjustable oscillator Soft start function at power-up Pulse-by-pulse overcurrent protection Thermal shutdown 5000 V rms isolation High common-mode transient immunity: >25 kV/μs 16-lead SOIC package with 8.3 mm creepage High temperature operation: 105°C maximum Safety and regulatory app.
