ZLED7015KIT-E1

The ZLED7015KIT-E1 is an evaluation kit which provides a quick and easy method for evaluating the ZLED7015 within its basic application circuit. The ZLED7015 is a constant current boost converter with an internal FET switch. The step up converter topology allows series connection of multiple white LEDs so that the LED currents are identical for uniform brightness. The ZLED7015 IC is designed for LED current drive applications of up to 1.8A. The evaluation board contains a standard 4 pin terminal connector to allow the user to easily connect and supply an LED's board. A 10µH shielded inductor sets the nominal frequency around 300KHz. The shielded inductor has been selected to minimize radiated EMI. The layout with any switching regulator is crucial to minimize radiated EMI. This reference design keeps the critical track lengths to a minimum. The Evaluation Board requires a DC power supply of 6V for the LED string, but it also must be 3V higher than the normally working output voltage.
