The PMP20795 reference design uses UCC256301 enhanced LLC controller with integrated driver to provide 24V/12A output from a nominal 380VDC input. UCC256301 provides hybrid hysteresis control (HHC) to enable a fast transient response. In this design, a 1st order system with over 6kHz bandwidth is achieved. In addition, the advanced burst mode allows this converter to achieve less than 200mW power consumption at no load. With 200kHz nominal switching frequency, the converter is able to achieve over 96% peak efficiency.
