Texas Instruments UCC28730 | Demoboard PMP41063
300-V-1,000V input 48-W isolated auxiliary power reference design with low standby power
Overview
| Topology | Flyback Converter |
| Input voltage | 300-1000 V |
| Output 1 | 12 V / 4 A |
| IC revision | 001 |
Description
This reference design provides an isolated 12-V, 48-W output power conversion with cascaded flyback topology. The power supply can be powered from the 300-V to 1,000-V direct current (DC) input. This design uses valley switching flyback controller UCC28730 to achieve less than 70-mW low standby power consumption at 1,000-V input voltage to extend the battery lifetime.
Features
- Wide input-voltage range from 300-V to 1,000-V input voltage
- Less than 70-mW no-load power consumption at 1,000-V input voltage
- Primary-side regulation design (no optocoupler) extend product lifetime
- Minimized output undershoot and overshoot during load transient
- Uniform start-up time across input voltage range
- 86.14% efficiency at 1,000-V input and 48-W output
Typical applications
- 300V-1000V input 48-W isolated auxiliary power
