The TPS92365xEVM provides an LED driver based on the TPS92365x boost/buck-boost switching regulator. It is designed to operate with an input voltage in the range of 4.5 V to 65 V. The EVM is set up for a default output current of 2 A and can work in four configurable dimming options. Please refer to TPS92365x datasheet (literature number: SLVSGH1) for more detailed information on configurable dimming options. By applying 0-100% duty cycle PWM signal on ADIM/HD pin or PWM/EN pin, device is able to operate in analog dimming or PWM dimming respectively. For analog dimming, it can provide dimming ratio up to 256:1. For PWM dimming, it can output pulse with width down to 200 ns. The TPS92365x integrates hybrid dimming mode that combines analog dimming and PWM dimming with a fixed transition point (1/8 target current) to maximize dimming performance. To further increase the flexibility of dimming control, flexible dimming mode is also available to independently control LED current value and the on/off behavior. The TPS92365x can provide features like wide voltage range, high current rating and ultra-deep dimming range.
