3 Description

The TPS92200D1/D2RXLREVM provides an LED driver based on the TPS92200 buck regulator. It is designed to operate with an input voltage in the range of 4.0 V to 30 V. The EVM is set up for a default output current of 0.5 A. For TPS92200D1RXLREVM, it can work either in analog dimming mode with analog input(0.65V to 1.2V) or PWM dimming with 100Hz to 2kHz, 0-100% duty cycle PWM input. For TPS92200D2RXLREVM, it works in analog dimming mode with 20kHz to 200kHz, 0-100% duty cycle PWM input. See the TPS92200 data sheet (SLUSER4) for more information about choosing dimming mode and components selection. The forward voltage of the LED load is between approximately between 1.0 V and 30 V (depending on the input voltage). The TPS92200 helps provide high efficiency, wide dimming range, good line regulation, and low output ripple LED driver.
