Uniquely Efficient Isolated DC/DC Converter for Ultra-Low Power and Low Power Apps Reference Design

Description


The TIDA-00349 TI Design is an isolated DC/DC converter turn-key solution, delivering exceptionally high efficiencies up to 85% from ultra-low power up to 60mW. Open-loop control removes the need for opto-couplers, while a primary side half-bridge topology operating at 60kHz and secondary side Schottky rectification provides low switching losses, enabling highly efficient power conversion. The single side populated PCB board provides a convenient tool for evaluation and on-the-fly optimization of the design, with adequate headers, jumpers and test points for covering a wide variety of applications.
