Monolithic Power Systems EV4021A-S-00T

Description

The EV4021A-S-00T Evaluation Board is designed for driving a nominal LED string voltage of 50V at 0.3A from universal input (85VAC-265VAC). The LED driver uses the MP4021A.

The MP4021A is a primary-side-control offline LED lighting controller which can achieve high power factor and accurate LED current for anisolate lighting application in a single stage converter. It works in boundary conduction mode for reducing the MOSFET and Diodeswitching losses.

The EV4021A-S-00T has a low profile and high efficiency, and meets IEC61547 surge immunity, IEC61000-3-2 Class C harmonics andEN55015 conducted EMI requirements. It has multi-protection function such as over-voltage protection, short-circuit protection, cycle bycycle current limit, etc.

Features

• Low profile design, <10mm component height
• Unique architecture for superior line regulation
• High power factor>0.9 over universal input voltage
• Boundary conduction mode improves efficiency
• Input UVLO
