ADuM3070 - Isolated Switching Regulator

Datasheet Summary

Description

The ADuM30701 isolator is a regulated dc-to-dc isolated power supply controller with an internal MOSFET driver.

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

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 80% efficiency 200 kHz to 1 MHz adjustable oscillator Soft start function at power-up Pulse-by-pulse overcurrent protection Thermal shutdown 2500 V rms isolation High common-mode transient immunity: >25 kV/µs 16-lead QSOP package High temperature operation: 105°C.
