The ZLED7xx0 LED Driver families with integrated switches drive single or multiple LEDs from a supply voltage range of 6-40V using continuous-mode inductive step-down (Buck) converters. TheZLED7000, ZLED7020, ZLED7320, ZLED7520 and ZLED7720 have PWM & DC dimming capabilities and output currents from 0.35A to 1.2A. The ZLED7030, ZLED7330, ZLED7530 and ZLED7730 provide switch dimming capability and outputs currents from 0.35A to 1.2A. The ZLED7010 includes a temperature compensation function, PWM & DC dimming and output current 0.75A.

In applications driving strings of multiple High Brightness (HB) LEDs from a low voltage source, theZLED7015 provides the necessary step-up (Boost) functionality. It is optimized for cost and space sensitive applications with its integrated switch, PWM & DC dimming. It also has numerous safety features including open/short circuit protection, under/over-voltage protection and over temperature protection. An integrated soft-start function minimizes in-rush current during startup and helps extend the LED lifetime.

For line-powered applications, the ZLED7001 universal LED driver allows efficient operation of High Brightness (HB) LEDs with voltage sources ranging from 8 Vdc to 450 Vdc, including rectified 110 Vac / 220 Vac. In addition the ZLED7001 has PWM & Linear dimming functions and a temperature compensation input to ensure maximum LED lifetime.

The ZLED7002 is a unique toggle dual-channel LED that operates in the lower DC voltage supply range of 2.7-5.5V. The ZLED7002 enables low-power battery-driven lighting applications that require switching to a lower-current LED channel when the supply is low, helping extend the lighting life-time. The ZLED7002 is also suitable for voltage-level indicator applications.

The ZLED7012 and ZLED7022 incorporate low-noise, constant-frequency charge pump DC/DC converters that can efficiently drive up to four (ZLED7012) or six (ZLED7022) strings of LEDs with DC voltage supplies ranging from 2.8V to 5.5V designed for battery-powered handheld devices.

All devices have very small footprints and are highly integrated thus enabling a very low bill of materials (BOM) cost.
