LP8868YQ1EVM
概述
The LP8868YQ1EVM helps designers evaluate the operation and performance of the LP8868Y-Q1, a nonsynchronous buck-boost switching regulator designed for high-current LED driver applications. The LP8868Y-Q1 provides 4A nonsynchronous buckboost LED driver functionality. The device features a wide input voltage range from 4.5V to 65V. The component offers four dimming options: analog dimming, PWM dimming, hybrid dimming, and flexible dimming. Each dimming mode can be configured through the PWM or EN and ADIM or HD input pins by simple high and low signals. The EVM also provides full protections, including LED open protection and short protection, sense resistor open protection and short protection, configurable thermal foldback, and thermal shutdown.
