Small, Unniversal Input Non-Isolated Off-Line Regulator Evaluation Board
Overview
| Topology | Buck Converter |
| Input voltage | 85-265 V |
| Output 1 | 5 V / 0.12 A |
| IC revision | 1.0 |
Description
The EV172-S-00A Evaluation Board is designedto demonstrate the capabilities of MP172. TheMP172 is a primary-side constant voltageregulator providing accurate constant voltage(CV) regulation without Opto-coupler. Itsupports Buck, Buck-Boost, Boost and Flybacktopologies.The EV172-S-00A Evaluation Board is designedas Buck application. EV172-S-00A typicallydrives 5V/120mA load from 85VAC to 265VAC,at 60/50Hz.The EV172-S-00A has an excellent efficiencyand meets IEC61000-4-5 2kV surge immunityand EN55022 conducted EMI requirements.MP172 features various protections, includingthermal shutdown (TSD), VCC under-voltagelockout (UVLO), over-load protection (OLP),short- circuit protection (SCP), and open loopprotection.MP172 is available in TSOT23-5 and SOIC8package.
