The MP4054 is a non-isolated, offline LED lighting controller. In a tiny TSOT23-8 package, it achieves high power factor (PF) and accurate LED current for isolated, single-power-stage lighting applications.
The MP4054 integrates power factor correction (PFC) and valley switching mode to reduce MOSFET switching losses.
To enhance system reliability and safety, the MP4054 has multiple internally integrated protection features, including over-voltage protection (OVP), short-circuit protection (SCP), over-current protection (OCP), brown-out protection, over-temperature protection (OTP), cycle-by-cycle current limit, VCC under-voltage lockout (UVLO), and auto-restart function.

The EV4027-J-01A Evaluation Board is designed to demonstrate the capabilities of MP4027. The MP4027 is a primary-side-control offline LED lighting controller which can achieve high power factor and accurate LED current for an isolated lighting application in a single stage converter. It works in boundary conduction mode for reducing the MOSFET and Diode switching losses.
The EV4027-J-01A is typically designed for driving an isolated 7W A19 LED bulb with 20VTYP, 350mA LED load at universal input (90V~265VAC, 50/60Hz).
The EV4027-J-01A has high performances in efficiency, line/load regulation and meets IEC61547 surges, IEC61000-3-2 Class C harmonics and EN55015 conducted EMI. It has multi-protection function as over-voltage protection, short-circuit protection, primary-side OCP, NTC, etc.
