Texas Instruments TL2842BDR-8 | Demoboard PMP22899
24-W, 120-VAC to 24-VDC buck converter reference design
Overview
| Topology | Buck Converter |
| Input voltage | 108-132 V |
| Output 1 | 24 V / 1 A |
Description
This reference design uses a TL2842B as a high-side buck to convert a 120-Vac input to a 24-Vdc output capable of 1-A loading. At full load, it acheives a low peak-to-peak output ripple and over 88% efficiency at full load. This reference design was built using a 2-layer PCB and single-sided assembly.
Features
- Less than 50-mV peak-to-peak output ripple
- Over 88% efficiency at full load
- Compact 2.75" x 2.5" PCB with 0.84" component maximum height
Typical applications
- AC-input BLDC motor drive
