3 Description

The TPS922152EVM provides an LED driver based on the TPS922152 buck switching regulator. The EVM is set up for a default output current of 5A with analog and PWM dimming options. By applying 0-100% duty cycle PWM signal on PDIM pin or analog voltage in the range of 0.2V to 2.4V on ADIM pin, device is able to operate in PWM dimming or analog dimming respectively. For analog dimming, the EVM can provide dimming ratio up to 1000:1. For PWM dimming, the EVM can output pulse with width down to 50ns. 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 TPS92215x can provide features like wide voltage range, high current rating and ultra-deep dimming range.
