Texas Instruments UCC28600 | Demoboard PMP40473
85 - 115-Vac input to isolated three-output flyback reference design for washing machines
Overview
| Topology | Flyback Converter |
| Input voltage | 85-115 V |
| Output 1 | 15 V / 0.02 A |
| Output 2 | 24 V / 0.5 A |
| Output 3 | 12 V / 1 A |
Description
This is a quasi-resonance (QR) flyback reference design for industrial applications, which illustrates how to convert AC input voltage 85 - 115 Vac to isolated multiple outputs: 24 V/0.5 A, 12 V/0.9 A and 15 V/20 mA using the UCC28600 Controller. The quasi-resonant switching of the UCC28600 allows this design to achieve peak efficiency of up to 87.5% while the no-load losses are less than 82 mW.
Features
- Generates multiple isolated output voltages which mitigates noise between outputs
- Enables standby operation with low power consumption (less than 82 mW) at no load
- Provides efficient power conversion with greater than 87.5% peak efficiency
