Product Description

The MP4026 is a primary-side-control, offline LED controller that achieves high-power factor and accurate LED current for isolated, single-power-stage lighting applications in an FCTSOT package. It is the next generation of the successful MP4021A.  The proprietary real-current-control method accurately controls LED current from primary-side information with good line and load regulation. The primary-side-control eliminates the secondary-side feedback components and the opto-coupler to significantly simplify LED-lighting-system design. The MP4026 integrates power-factor correction and works in boundary-conduction mode to reduce MOSFET switching losses. The MP4026’s multiple protection features greatly enhance system reliability and safety. These features include over-voltage protection, short-circuit protection, primary-side over-current protection, brown out protection, cycle-by-cycle current limiting, VCC under-voltage lockout, and auto-restart over-temperature protection.

Evaluation Kit


Kit details

The EV4026-J-00A Evaluation Board is designed to demonstrate the capabilities of MP4026. The MP4026 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 EV4026-J-00A is typically designed for driving an isolated 7W A19 LED bulb with 20VTYP, 350mA LED load at universal input (90V~265VAC, 50/60Hz).

The EV4026-J-00A 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, etc.
