1 Introduction

The TPS92205x EVM 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 2-A/4-A non-synchronous buck LED driver and features a wide input voltage range (4.5-V to 65-V) and four dimming options, including analog dimming, PWM dimming, hybrid dimming and flexible dimming. Each dimming mode can be configured through the PWM/EN and ADIM/HD input pins by means of simple high/low signals. It also provides full protections, including LED open protection and short protection, sense resistor open protection and short protection, configurable thermal foldback and thermal shutdown. The TPS92205x EVM evaluation module (EVM) series include TPS922055DMTREVM, TPS922055DRRREVM and TPS922053DYYREVM.
