The ADuM3070 isolator is a regulated dc-to-dc isolated power supply controller with an internal MOSFET driver. The dc-to-dc controller has an internal isolated PWM feedback from the secondary side based on the iCoupler® chip scale transformer technology and complete loop compensation. This eliminates the need to use an optocoupler for feedback and compensates the loop for stability. The ADuM3070 isolator provides a more stable output voltage and higher efficiency compared to unregulated isolated dc-to-dc power supplies. The fully integrated feedback and loop compensation in a small QSOP package provides a smaller form factor than any discrete solution. The regulated feedback provides a relatively flat efficiency curve over the full output power range. The ADuM3070 enables a dc-to-dc converter with a 3.3 V to 24 V isolated output voltage range from either a 5.0 V or a 3.3 V input voltage, with an output power of up to 2.5 W. Applications * Power supply startup bias and gate drives * Isolated sensor interfaces * Process controls * 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 https://elecena.pl/product/2940935/isolated-switch-regulator-with-integrated-feedback 2012-05-10 https://elecena.pl/product/2940935/isolated-switch-regulator-with-integrated-feedback 2018-03-28 https://elecena.pl/product/2940935/isolated-switch-regulator-with-integrated-feedback 2025-01-22
