The TPS92205DRRR evaluation module (EVM) helps designers evaluate the operation and performance of the TPS92205x non-synchronous buck switching regulator designed for high-current and ultra-deep dimming ratio LED driver applications. The TPS92205x is a 2A/4A non-synchronous buck LED driver and features a wide input voltage range (4.5V to 65V) and four dimming options, including analog dimming, PWM dimming, hybrid dimming and flexible dimming.
