The NCP1381DR2G is an offline switching controller from On Semiconductor designed for flyback topologies. It is housed in a 14-pin SOIC package and provides isolated output regulation.
The device operates over a supply voltage range of 10V to 20V. It features an extremely low startup current of 15 mA maximum, enabling efficient power-up. The peak current drive capability is +500 mA sourcing and -800 mA sinking, suitable for driving external MOSFETs. An internal 5 ms soft-start management reduces inrush stress. The built-in 5V/10mA reference voltage simplifies biasing.
Comprehensive fault protection includes over-load, over-temperature, over-voltage, and short-circuit protection. The controller is suitable for AC-DC converters, adapters, and auxiliary power supplies requiring isolated flyback conversion.
The NCP1381DR2G is offered in a 14-SOIC package with an operating temperature range of 0°C to 125°C junction temperature.
