Design and development of hybridized point of load converters for FPGA applications

This paper complies design and development of hybridized Point of Load (POL) converter for distributed load power system. In this proposed converter, LM2743 - synchronous buck controller IC is employed, to achieve high efficiency for low voltage, high current applications. The LM2743 IC has output under and over voltage detection circuit, in-built bootstrap circuit and shutdown features. The proposed POL converters having an input range of 5V-15V with an efficiency of 93% and operates at switching frequency of 300 KHz. It has special feature of output voltage trimming so output voltage can be set in range between 0.8V to 3.3V. This is implemented on a hardware prototype and experimental results are tabulated.
