LED lamps and bulbs can have a number of different form-factors depending on the specific use, size and dimension of the application including retrofit bulbs, high-bay lights, low-bay lights, emergency lights. Driving a string of LEDs has to do with AC-DC and DC-DC conversion – designed using non-isolated, isolated, single stage or multi-stage topologies – that has to ensure high efficiency and reliability obtained at a competitive cost point.

We have a range of pulse-width modulation (PWM) and power factor correction (PFC) controllers, power MOSFETs and diodes as well as a comprehensive set of hardware evaluation and development tools including reference designs to help developers design high-efficiency LED lighting solutions.
