MP4054A

Primary-Side Control, Offline LED Controller with Active PFC, NTC and PWM Dimming

Datasheet

Description

The MP4054A is a primary-side-control, 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.
This simplifies LED-lighting-system design significantly by eliminating the secondary-side feedback components and the optocoupler.
The MP4054A integrates power factor correction (PFC) and valley switching mode to reduce MOSFET switching losses.
The MP4054A has NTC function and allows PWM dimming.
To enhance system reliability and safety, the MP4054A has multiple internally integrated protection features, including over-voltage protection (OVP), short-circuit protection (SCP), primary-side 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.
