MP4054AGJ-P Monolithic Power Systems

MP4054A Primary-Side Control, Offline LED Controller with Active PFC, NTC and PWM Dimming DESCRIPTION FEATURES The MP4054A is a primary-side-control, offline Real-Current Control without Secondary- LED lighting controller. In a tiny TSOT23-8 Feedback Circuit package, it achieves high power factor (PF) and <2% Line/Load Regulation accurate LED current for isolated, single-power- NTC Thermal Current Fold-Back stage lighting applications. PWM Dimming Available High PF (0.9) over Universal Input Voltage This simplifies LED-lighting-system design Valley Switching Mode for Improved significantly by eliminating the secondary-side Efficiency feedback components and the optocoupler. Brown-Out Protection The MP4054A integrates power factor Over-Voltage Protection correction (PFC) and valley switching mode to Short-Circuit Protection reduce MOSFET switching losses. Over-Temperature Protection The MP4054A has NTC function and allows Primary-Side Over-Current Protection PWM dimming. Cycle-By-Cycle Current Limit VCC Under-Voltage Lockout Protection To enhance system reliability and safety, the Auto-Restart Function MP4054A has multiple internally integrated Available in TSOT23-8 Package protection features, including over-voltage protection (OVP), short-circuit protection (SCP), APPLICATIONS primary-side over-current protection (OCP), brown-out protection, over-temperature Solid-State Lighting protection (OTP), cycle-by-cycle current limit, Industrial and Commercial Lighting VCC under-voltage lockout (UVLO), and auto- Residential Lighting restart function.
