EV4057A-K-00A Evaluation Kit 198VAC to 265VAC/50Hz, 21V/370mA + 3.3V/50mA Single-Stage, Single-Chip Solution for Smart LED Evaluation Board
The EV4057A-K-00A evaluation board is designed to demonstrate the capabilities of the MP4057A. The MP4057A is a single-stage, single-chip solution for smart LED applications. It can regulate the LED current with PSR control, and meanwhile supply power for MCU/wireless module. It is an ideal solution for smart LED lighting because of its simple design, few external components, and low cost.
The EV4057A-K-00A adopts the flyback topology to drive a 21V LED and supply a 3.3V/50mA smart control module.
Determined by the customer specification about the standby power, the EV4057A-K-00A can be configured for two kinds of circuits. The default EVB board is designed for less than 30mW standby power. It can also be configured for 15mW standby power.
