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

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(1) These are stress ratings only. Stress beyond these limits may cause permanent damage to the device. Functional operation of the
device at these or any conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to
absolute maximum rated conditions for extended periods of time may affect device reliability
(2) Voltage on VCG is internally clamped. The clamp level varies with operating conditions. In normal use, VCG is current fed with the
voltage internally limited
(3) In normal use, OTM, PCL, VSD, and FB are connected to resistors to GND and internally limited in voltage swing

(1) Tested per JEDEC EIA/JESD51-1. Thermal resistance is a function of board construction and layout. Air flow reducex thermal
resistance. This number is included only as a general guideline; see TI document (SPRA953) IC Package Thermal Metrics.
(2) Thermal resistance to the circuit board is lower. Measured with standard single-sided PCB construction. Board temperature, TB,
measured approximately 1 cm from the lead to board interface. This number is provided only as a general guideline.
