PMP23649
40W, 48V-to-1kV nonisolated DCM flyback converter reference design
PMP23649
概覽
This reference design is a high-conversion ratio flyback converter that steps up a 48V input to a regulated 960V output. The single stage solution acheives less than 0.5% output ripple with minimal output capacitance used. LM5156 is used to implement the non-synchronous current-mode control design. RES60A500-Q1 scales the output voltage to a safe level for the PWM controller.
特點
- Low profile design, 12 mm max component height
- <0.5% output ripple
- Single-side assembly with 2-layer PCB design
