Texas Instruments UCC2897A | Demoboard PMP7294
18Vdc-36Vdc Input, 28V/100W Active Clamp Forward (ACTIVE) PMP7294
Overview
| Topology | Forward Converter |
| Input voltage | 18-36 V |
| Output 1 | 28 V / 3.6 A |
| IC revision | B |
Description
This reference design uses the UCC2897A active clamp controller to generate an isolated 28V/3.6A output from a standard 24Vdc telecom input. This design uses diode rectification on the output stage and achieves efficiencies up to 93%. The output is adjustable down to 24V by changing a single resistor value.
Features
- 18-36V Input, 28V/3.6A Output
- Standard 24Vdc telecom input range
- Efficiency up to 93%
- Diode Rectification
- Adjustable Output as low as 24V
- Active Clamp Forward Topology, featuring UCC2897A Controller
