This document describes the design example of a power supply using the STR3A453D intended for the non-isolated buck converter that supports universal inputs and a 15 V/0.7 A output (0.8 A peak). The STR3A453D is a current mode PWM control IC with a built-in power MOSFET, developed for isolated flyback converters. However, the IC is also suitable for configuring non-isolated buck converters. In addition, the design example uses the SJPD-L5 as a fast recovery diode for the freewheeling diode, and the SJPD-D5 as a fast recovery diode for the IC’s power supply.This document contains the following: the specifications of the design example, circuit diagrams, the bill of materials, the setting examples of component constants, a pattern layout example, and the evaluation results of the power supply characteristics. For more details on the parts listed in this document, refer to the corresponding data sheets.
