Product Overview

The TPS92010EVM-592 is an evaluation module designed to evaluate TPS92010 high efficiency offline LED lighting driver controller. The power topology is a quasi resonant mode flyback. This makes for a cost competitive solution. This TPS92010 EVM implements a constant current, high efficiency, low ripple AC to DC LED lighting driver. The high efficiency is maintained even during deep dimming. Current sensing is done directly via a resistor and op amp. This in turn drives an opto coupler which sets the PWM pulses via the TPS92010 to control the output current at a constant level. The design also incorporates a circuit to ensure compatibility with a large number of commonly available TRIAC based dimmers. This circuit monitors the line voltage for TRIAC operation. When the TRIAC is operating the line voltage is chopped. This information is used by the circuit to reduce the constant output current level thus dimming the LED's.
  • TRIAC compatible dimming
  • Low cost line powered LED driver solution
  • Includes 5 HB-LED's as a sample load
  • Allows easy use of user own LED load
  • Test points for LED voltage and current
  • Accurate current sensing to maintain constant current to LED's
  • Modifiable output current from 0.2A to 0.7A, 0.325A is default
