TIDA-00349
適用於超低功耗與低功耗應用的獨特效率隔離式 DC/DC 轉換器參考設計
TIDA-00349
概覽
This reference design is an isolated DC/DC converter turn-key design that delives high efficiency up to 85% from ultra-low power up to 60 mW. Open-loop control removes the need for opto-couplers, while a primary side half-bridge topology operating at 60 kHz 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.
