The PTH03030 is a series of highcurrent non-isolated power modules from Texas Instruments. The product is characterized by high efficiencies, and up to 30 A of output current, while occupying a mere 1.64 in of PCB area. In terms of cost, size, and performance, the series provides OEM's with a flexible module that meets the requirements of the most complex and demanding mixedsignal applications. These include the most densly populated, multi-processor systems that incorporate high-speed DSP's, microprocessors, and ASICs. The series uses double-sided surface mount construction and provides highperformance step-down power conversion from a 3.3-V input bus voltage. The out-
