SSL5018TE
SSL5018TE is Compact non-dimmable LED driver IC manufactured by NXP Semiconductors.
description
The SSL5018TE is a high-voltage Integrated Circuit (IC) controller with an integrated MOSFET for driving LED lamps in general mains non-dimmable lighting applications. The IC operates with input voltages up to 230 V (AC).
The main benefits of these products are:
- Small Printed-Circuit Board (PCB) footprint, and pact solution
- High efficiency (up to 93 %)
- High input power factor (> 0.95); Low Total Harmonic Distortion (THD; < 20 %)
- Intermediate power factor (PF > 0.7); low ripple (< 5 %); minimum external ponent count
- Enhanced power capability
- Low electronic Bill Of Material (BOM)
The SSL5018TE operates in Boundary Conduction Mode (BCM) with peak current modulation, providing an input power factor correction. The IC is typically configured to a buck converter. It can start up directly from the HV pin using an internal high-voltage current source. When the converter is switching, VCC is supplied through the DVDT pin by a capacitor coupled to the DRAIN pin or by an auxiliary supply. This feature simplifies the VCC supply. It allows a low-cost off-the-shelf inductor to be used, providing flexibility in application design. The IC supply current is 1.3 m A.
The SSL5018TE es in a pact HSO8 package incorporating an exposed pad to enhance the thermal capability for high-power applications, like 18 W T-LEDs or higher power lamps.
