40-V to 180-V DC input: 24-V 2-A output half brick power module reference design
Description
This reference design is an auxiliary power supply with 24-V: 2-A output. The line and load regulation of the power supply is designed to be within 1% using secondary side regulator UCC28740. All components are on the toplayer and the size is the industrial standard half-brick dimension.
Features
- Valley switching operation and VS balance synchronous rectifier flybackSecondary-side feedback improve load regulationAll components on the toplayer simplify adding heatsink on the bottom sideIntegrated input OVP: UVLO: and output OVP: OCP: SCP improve system reliability
Applications
- Oscilloscopes & digitizers
- Railway electric propulsion
