ZLED7001 Universal LED Driver with Temperature Compensation Datasheet Brief Description ZLED7001 Features The ZLED7001, one of our ZLED family of LED control Wide input range from 8 VDC to 450 VDC or ICs, is a peak current-mode control LED driver IC that is 110 VAC/220 VAC optimal for buck LED driver applications. The ZLED7001 Temperature compensation to protect the LEDs and operates in constant off-time mode. Capable of extend LED lifetime operating efficiently with voltage sources ranging from 8 Operates in constant off-time mode VDC to 450 VDC or rectified 110 VAC/ 220 VAC, it is Both PWM and linear dimming control signal inputs ideal for High Brightness (HB) LED applications. The available ZLED7001 provides a PWM input for an external dimming control signal. The ZLED7001s linear dimming Very few external components needed for operation input can be used both for linear dimming (0 to 240 mV) Broad range of applications: outputs greater than 1A and temperature compensation of the LED current. Because the ZLED7001s response time is limited only Application Examples by the rate of change in the inductor current, it attains a high performance pulse-width modulation (PWM) dim- Line-powered replacement LED lighting ming response. The ZLED7001 ensures proper output Illuminated LED signs and other displays current regulation, without loop compensation, via peak LED street and traffic lighting current-mode operation.
