DESCRIPTION

The MP4088 is a highly integrated, TRIAC

dimmable LED driver with an integrated 500V

MOSFET that regulates precise LED currents in

non-isolated lighting applications and requires

only a single winding inductor. The MP4088

features MPS’ proprietary hybrid operation

mode, which is designed to achieve optimal

dimming

performance.

The

MP4088

is

designed

specifically

for

high-line

input

(230VAC) and TRIAC dimmable LED lighting

applications, especially for low-cost and small

form-factor applications.

The accurate output LED current is achieved by

an internal averaging current feedback loop. An

internal high-voltage regulator makes the

MP4088 start up quickly without a perceptible

delay.

The

power

de-rating

at

high

temperatures makes the system flicker-free

when the ambient temperature is high.

Full protections features include VCC under-

voltage lockout (UVLO), over-voltage protection

(OVP), and short-circuit protection (SCP). All of

these features make the MP4088 an ideal

solution for simple, offline, and non-isolated

TRIAC dimmable LED lighting applications.

The MP4088 is available in TSOT23-5, SOIC8-

7A, and SOIC-8 EP packages.
