TPS92001EVM-628

Using the TPS92001EVM-628 User's Guide Literature Number: SLUU897 March 2012 User's Guide SLUU897 – March 2012 Dimmable LED Lighting Driver Controller 1 Introduction The TPS92001EVM-628 evaluation module is a constant-current, dimmable LED driver. It is designed to drive 9 LEDs at 330 mA and is rated for an AC input of 105 VRMS to 135 VRMS. 2 Description The TPS92001/2 family of general LED lighting PWM controllers contains control and drive circuitry required for off-line isolated or non-isolated LED lighting applications. The TPS92001EVM-628 evaluation module uses the TPS92001 as a non-isolated buck controller; more specifically it is an inverting buck topology. The controller operates in fixed-frequency, current-mode switching with minimal external parts count. In LED illumination applications there is typically no need for the LED load to be referenced to ground. This utilizes the inverted buck which moves the controller and FET to the low side of the circuit, referenced to the lowest voltage, while the LED load is floated (referenced to the highest voltage). With an appropriately designed bias regulator for the controller, we can now use a much lower voltage controller which is more economical. 2.1 Typical Applications • 2.2 Features • • • • 3 Commercial/Household LED Lighting Dimmable, Non-Isolated LED Driver with Minimum External Part Count Wide-Duty Cycle Range for Wide-Input Voltage Convenient 5-V Reference Output Test Points for Output Voltage/Current Electrical Performance Specifications Table 1.

You will take care of proper disposal and recycling of the EVM’s electronic components and packing materials. Certain Instructions. It is important to operate this EVM within TI’s recommended specifications and environmental considerations per the user guidelines. Exceeding the specified EVM ratings (including but not limited to input and output voltage, current, power, and environmental ranges) may cause property damage, personal injury or death. If there are questions concerning these ratings please contact a TI field representative prior to connecting interface electronics including input power and intended loads. Any loads applied outside of the specified output range may result in unintended and/or inaccurate operation and/or possible permanent damage to the EVM and/or interface electronics. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures greater than 60°C as long as the input and output are maintained at a normal ambient operating temperature. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors which can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during normal operation, please be aware that these devices may be very warm to the touch.
