ISSI IS32LT3175P-GRLA3-EB Evaluation Board is a fully assembled and tested board that uses the IS32LT3175 single channel linear LED driver. The IS32LT3175 is a single channel linear programmable current regulator capable of up to 150mA. The driver integrates a debounce and the latch circuit on the channel enable pin (EN) to facilitate the use of a low-cost momentary contact switch. The PWM pin can be interfaced to a logic level “courtesy light” signal to directly drive the LED channel.
