IRDC3039EVAL

The IRDC3039EVAL controller IC is designed to provide a synchronous Buck regulator and is targeted for applications where the cost and size is critical. The IRU3039 operates with a single input supply up to 20V. The output voltage can be programmed as low as 0.8V for low voltage applications. Selectable current limit is provided to tailor to external MOSFET's on-resistance for optimum cost and performance. The IRDC3039EVAL features an uncommitted error amplifier for tracking output voltage and is capable of sourcing or sinking current for applications such as DDR bus termination.

This IRDC3039EVAL features a programmable switching frequency set from 200KHz to 400KHz, under-voltage lockout for both Vcc and Vc supplies, an external programmable soft-start function as well as output under-voltage detection that latches off the device when an output short is detected.
