SSL5015TE LED Driver

Mouser Electronics is now stocking the SSL5015TE LED Driver IC from NXP Semiconductors. Engineered to drive LED lamps for general mains non-dimmable light applications, this high-voltage, integrated controller and MOSFET provides enhanced power functionality with up to 93 percent efficiency. On-chip protection circuits improves reliability in high-power applications such as 18 W T-LEDs or higher power lamps. This compact solution provides a small PCB footprint and a low Bill of Materials (BOM).

The NXP SSL5015TE LED Driver Integrated Circuit (IC), available from Mouser Electronics, targets 100VAC or 120VAC systems and boasts an input power factor that is greater than 0.95, with a low Total Harmonic Distortion (THD) of less than 20 percent. Requiring minimal external component count, the SSL5015TE provides an intermediate power factor (PF) of greater than 0.7, and a low ripple of less than 5 percent.

The SSL5015TE can be configured as a buck converter while drawing only 1.3 mA. The chip can start up directly from the HV pin using an internal high-voltage current source. While 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 not only simplifies the VCC supply, but it allows designers to incorporate a low-cost, off-the-shelf inductor.

Other features of the SSL5015TE include an integrated switch mode LED driver with 300 VDC power switches, direct PWM current regulation, and fast transient response through peak current mode control. UnderVoltage LockOut (UVLO), OverCurrent Protection (OCP), Internal OverTemperature Protection (OTP) and Brownout protection circuits are also on-chip.
