The ADuM3070/ADuM4070 is a regulated DC/DC isolated power supply controller with an internal MOSFET driver. The DC/DC controller has an internal isolated PWM feedback from the secondary side. It is based on the iCoupler chip scale transformer technology and completes the loop compensation.
Feature
- 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
- 5000 V rms isolation
- High common-mode transient immunity: >25 kV/µs
- 16-lead SOICpackage with 8.3 mm creepage
- High temperature operation: 105°C
Applications
- Power supply startup bias and gate drives
- Isolated sensor interfaces
- Process controls
