The TPS92210 is a natural power factor correction (PFC) light emmitting diode (LED)
lighting driver controller with advanced energy features to provide high efficiency control for LED
A PWM modulation algorithm varies both the switching frequency and primary current while
maintaining discontinuous or transition mode operation in all regions of operation. The TPS92210
cascode architecture enables low switching loss in the primary side and when combined with the
discontinuous conduction mode (DCM) operation ensures that there is no reverse recovery loss in the
output rectifier. These innovations result in efficiency, reliability or system cost improvements
over a conventional flyback architecture.
The TPS92210 offers a predictable maximum power threshold and a timed response to an
overload, allowing safe handling of surge power requirements. The overload fault response is
user-programmed for retry or latch mode. Additional protection features include open-LED detection
by output overvoltage protection and thermal shutdown.
The TPS92210 is offered in the 8-pin SOIC (D) package. Operating junction temperature
range is –40°C to 125°C
