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
