SLUUBZ9 May 2020 TPS92200
The TPS92200D1/D2EVM provides an LED driver based on the TPS92200D1/D2 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 TPS92200D1EVM, 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 TPS92200D2EVM, it works in analog dimming mode with 20kHz to 200kHz, 0-100% duty cycle PWM input. See the TPS92200D1/D2 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 TPS92200D1/D2 helps provide high efficiency, wide dimming range, good line regulation, and low output ripple LED driver.
