0 `描述 This design is a LLC resonant half-bridge DC-DC power converter with digital control using 3138ACC32EVM-149 daughter-card. The daughter-card control functions with preloaded firmware providing the required control functions for a LLC resonant half-bridge converter. The TIDA-00512 (3138ALLCEVM-150) accepts a DC input from 350VDC to 400VDC, and outputs a nominal 12VDC with full load output power of 340W, or full output current of 29A. 特性 Synchronous rectification Optimal diode emulation and dead time of synchronous rectification Cycle-by-cycle current limiting with duty cycle matching Automatic mode switching between LLC mode and PWM mode Test points to facilitate device and topology evaluation TIDA-00512 Test Results.pdf (429.92 KB, 下载次数: 21 ) tidc932.zip (390.94 KB, 下载次数: 23 ) TIDA-00512 Assembly Drawing.pdf (320.79 KB, 下载次数: 14 ) TIDA-00512 BOM.pdf (120.83 KB, 下载次数: 9 ) TIDA-00512 Schematic.pdf (408.37 KB, 下载次数: 20 ) ` 1
