(example: Hewlett Packard 6813B AC power source). Power Meter: For accurate efficiency calculations, a power meter should be inserted between the AC source and the EVM. For highest accuracy, connect the voltage terminals of the power meter directly across the Line and Neutral terminals of the EVM. (example: Voltech PM100 Single Phase Power Analyzer). Multimeters: Two digital multimeters are used to measure the LED voltage (DMM VLED) and load current (DMM ALED). (example: Fluke 45 Digital Multimeter) Output Load: By connecting a jumper wire from J2 pin 2 to J2 pin 3 (LED RTN) the 5 Cree™ MX series white LEDs that are on the EVM may be used as the load. The EVM can also be used to drive the user’s external LED load by connecting the jumper wire from J2 pin 1 (+LED) to external 370 mA, 3.2-V LEDs and return them to J2 pin 3 (LED RTN). Oscilloscope: A 200-MHz digital oscilloscope with 4 isolated channels for differential mode measurements is required. Non-isolated probes may result in flickering. A high-voltage probe and a current probe are also recommended. (examples: Tektronix TPS2024B Four Channel Digital Storage Oscilloscope, Tektronix P5205A High-Voltage Differential Probe, Tektronix TCPA300 Amplifier AC/DC Current Probe) Dimmer: A leading edge dimmer, rated for 115 VAC can be used to controlling the LED light output. Fan: Forced air cooling is not required. Recommended Wire Gauge: A minimum of AWG 22 wire is recommended to connect the AC voltage source to the EVM at less than three feet long. WARNING High voltages that may cause injury exist on this evaluation module (EVM). Please ensure all safety procedures are followed when working on this EVM. Never leave a powered EVM unattended. LEDs will be very hot and very bright! Shaded protective eyewear is recommended. 6 Using the TPS92070EVM-682 Integrated Dimming LED Lighting Driver Converter for 115-VAC Input Copyright © 2011, Texas Instruments Incorporated SLUU698 – November 2011 Submit Documentation Feedback Test Setup www.ti.com 5.2 Recommended Test Setup DMM VLED AC SOURCE + LINE - NEUTRAL Dimmer POWER METER + - + VHI VLO AHI ALO + AEXT - DMM A LED Figure 2.
