A power supply capable of supplying 2 A must be connected to J1 through a pair of 20-AWG wires. The LED load must be connected to J2 through a pair of 20-AWG wires. The positive terminal of the LED load should be connected to the J2 terminal beside TP3 (VOUT), and the negative terminal of the LED load should be connected to the J2 terminal beside TP5. Wires should be twisted and kept as short as possible to minimize voltage drop, inductance, and EMI transmission.

TP7 is the input terminals for the Analog/PWM dimming signal. For TPS92200D1RXLREVM, If analog dimming mode is used, apply a DC voltage signal between 0.65V and 1.2V. If TPS92200D1RXLREVM is used, apply a square wave with a low level of GND and a high level voltage higher than 2 V, typically 3.3 V. The PWM frequency range is 100 Hz to 2 kHz, typically 1 kHz. For TPS92200D2RXLREVM, it only supports analog dimming mode, apply a square wave with a low level of GND and a high level voltage higher than 2 V, typically 3.3 V. The dimming frequency range is 20 kHz to 200 kHz.

Once the connection is ready, first apply the input voltage, then apply the Analog/PWM signal.
