Mouser – Peak current-mode universal LED driver for high-brightness applications (ZMDI - ZLED7001)Jul 23 2012 - Semiconductors [More Semiconductors Articles]
Now available from Mouser, ZMDI’s ZLED7001 Universal LED Driver is one of the company’s ZLED family of LED control ICs, and is a peak current-mode control LED driver IC that is optimal for buck LED driver applications.
The ZLED7001 operates in constant off-time mode. Capable of operating efficiently with voltage sources ranging from 8VDC to 450VDC or rectified 110VAC/ 220VAC, it is seen as ideal for high-brightness (HB) LED applications. The ZLED7001 provides a PWM input for an external dimming control signal. The ZLED7001′s linear dimming input can be used both for linear dimming (0 to 240mV) and temperature compensation of the LED current. Because the ZLED7001′s response time is limited only by the rate of change in the inductor current, it attains a high performance pulse-width modulation (PWM) dimming response. The ZLED7001 ensures proper output current regulation, without loop compensation, via peak current-mode operation.More news from Mouser
