Brief Description

ZLED7001 Features

The ZLED7001, one of our ZLED family of LED control

ICs, 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 8

VDC to 450 VDC or rectified 110 VAC/ 220 VAC, it is

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 240 mV)

and temperature compensation of the LED current.

• Wide input range from 8 VDC to 450 VDC or

110 VAC/220 VAC

• Temperature compensation to protect the LEDs and

extend LED lifetime

• Operates in constant off-time mode

• Both PWM and linear dimming control signal inputs

available

• Very few external components needed for operation

• Broad range of applications: outputs greater than 1A

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) dim-

ming response. The ZLED7001 ensures proper output

current regulation, without loop compensation, via peak

current-mode operation.

Application Examples

• Line-powered replacement LED lighting

• Illuminated LED signs and other displays

• LED street and traffic lighting

• Constant-current source for general purposes

• Architecture / building LED lighting

• LED backlighting

• Line powered LED flood lighting

• Interior / exterior LED lighting
