Current control & thermal design
Functional overview of an AC-powered LED driver. Protection, filtering, isolation and current regulation depend on the topology.
APPLICATION OVERVIEW
Understand the circuit requirements.
LED driver designs need an appropriate power conversion stage for the supply and the LED load. For an AC-powered driver, the input bridge is one part of that wider circuit.
The driver topology, input range, current waveform and enclosure temperature provide the context for rectifier selection. Package choice should be considered alongside the electrical ratings and the available thermal path.
DESIGN CONSIDERATIONS
The details behind component selection.
Startup current
Evaluate inrush from the input network. The non-repetitive IFSM rating has a specified test waveform and does not replace circuit-level startup evaluation.
Package constraints
Compare the PCB footprint and pin arrangement in the package drawing, as well as assembly and enclosure constraints.
Operating temperature
Review dissipation, ambient temperature and heat transfer in the completed driver. Read the conditions attached to current and thermal ratings.
COMPONENT SELECTION
A starting point for your design.
Bridge rectifiers illustrate package choices for input rectification. For switching stages that require an external high-voltage transistor, review the MOSFET category separately against the controller, gate drive and circuit stresses. Confirm voltage, current, surge and thermal performance for the complete driver.
