Texas Instruments UCD3138064A | Demoboard PMP23332
Interleaved and multiphase inverting buck-boost converter reference design
Overview
| Topology | FPGA |
| IC revision | A |
Description
This reference design uses the UCD3138064A as a digital controller to control inverting buck-boost with the capability of supporting two-phase peak current mode control. The soft-switching technology is used in this design to improve the power efficiency. The input voltage range is -62 V to -36 V. The output voltage range is adjustable from 28 V to 52 V. The default output voltage is 48-V with a maximum current of 14 A.
Features
- High efficiency above 97.1%
- Interleaved two-phase peak current mode (PCM) control
- Three phases with voltage mode (VM) control
- Zero voltage switching of MOSFETs
- Pre-biased start up
- Current balancing between phases
Typical applications
- Non-isolated battery backup unit
- Transformer-based DC/DC converter (100W~400W)
