Synchronous Pwm Controller For Termination Power Supply Applications - International Rectifier

The IRU3038 controller IC is designed to provide a low cost synchronous Buck Regulator for voltage tracking applications such DDR memory and general purpose on-board DC to DC converter. Modern micro processors combined with DDR memory, need high-speed bandwidth data bus which requires a particular bus termination volt- age. This voltage will be tightly regulated to track the half of chipset voltage for best performance. The IRU3038 together with dual N-Channel MOSFETs such as IRF7313 provide a low cost solution for such applications. This device features a programmable 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.
