Where to Use SSL5015TE LED Driver IC
The SSL5015TE is mainly used for low-cost mains non-dimmable LED lighting applications, including 18 W T-LEDs or higher power lamps, with a high power factor. The IC operates from 100 V (AC) or 120 V (AC) mains voltage. The output current can be modulated using a PWM signal.
How to Use SSL5015TE LED Driver IC
SSL5015TE is a BCM, peak current controlled system that operates at the boundary between continuous and discontinuous modes. A basic application diagram from the SSL5015TE datasheet is given below.
Inductor L is used to store the energy when MOSFET is turned on. The Drain current from the MOSFET is fed back to the sensing elements to maintain the stability of the upcoming output current. RSENSE resistor connected to the SOURCE pin is used to sense the current. The peak current sensed at the SOURCE2 pin determines when the MOSFET is switched off. When the internal MOSFET switches off, the current flows through the freewheeling diode and the output capacitor.
Applications of SSL5015TE
