MP4054AGJ-P

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.Applications:• Solid-State Lighting• Industrial and Commercial Lighting• Residential Lighting 9icnet Electronics is an authorized Monolithic Power Systems distributor.
