The TPS92200D2EVM evaluation module (EVM) helps designers evaluate the operation and performance of the TPS92200D2 synchronous buck switching regulator designed for high-current LED driver applications. The TPS92200D2 is a 1.5-A synchronous buck LED driver and features a wide input voltage range (4 V to 30 V), it supports analog mode dimming (1% to 100%) with PWM mode dimming (20 kHz to 200 kHz). For safety, protection systems are implemented, which include LED open/short protection, sense resistor open/short protection, and device thermal protection. To protect LED from over current damage, the driver will enter Hiccup protection mode once over current detected.
