IRDC3837 is an evaluation board which features the IR3837 synchronous buck regulator. It is a versatile regulator which offers programmability of switching frequency and current limit while operates in wide input and output voltage range. Internal LDO enables the device to operate from a single supply. This internal LDO can be bypassed when an external bias voltage is available. This board has protection functions such as pre-bias startup, hiccup current limit and thermal shutdown to give required system level security in the event of fault conditions. on board PWM controller and MOSFETs make IR3837 a space efficient solution by providing accurate power delivery. An output over current protection function is implemented by sensing the voltage developed across the on-resistance of the synchronous rectifier MOSFET.
