TPS92200D1EVM 的說明
The TPS92200D1EVM evaluation module (EVM) helps designers evaluate the operation and performance of the TPS92200D1 synchronous buck switching regulator designed for high-current LED driver applications. The TPS92200D1 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 analog input (0.65 V to 1.2 V), and PWM mode dimming (100 Hz to 2 kHz). For safety, kinds of protection are implemented, including 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.
