120Vac to 3.3Vdc, 0.5A coupled-inductor buck converter reference design
PMP23445
概述
This reference design demonstrates a buck converter using UCC28881 that converts a 120Vac input to a 3.3Vdc output. The use of a coupled inductor helps maintain a longer on-time while achieving an extreme conversion ratio for a non-isolated topology. Like other buck topologies, this design makes a low-voltage ripple output while using minimal output capacitance.
特性
- Less than 62mV peak-to-peak ripple on regulated 3.3Vdc output
- Single-side assembly PCB
- Compact solution can fit in a 0.75" x 1.75" area
