IRDC3637EVAL

The IRDC3637EVAL controller IC is designed to provide a low cost synchronous Buck regulator for on-board DC to DC applications in a small 8-pin SOIC. The output voltage can be precisely regulated using the internal 0.8V reference voltage for low voltage applications.

The IRDC3637EVAL operates at a fixed internal 400KHz switching frequency to reduce the component size.

The device features under-voltage lockout for both input supplies, an external programmable soft-start function as well as output under-voltage detection that latchesoff the device when an output short is detected.

The reference board of the IRDC3637EVAL is designed for 1.8V output using +5V and +12V supplies. This will demonstrate the main features of IC.
