DESCRIPTION
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 lighting applications.
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
