The ZLED7x20 is designed for applications requiring features such as high-speed switching, variable brightness
control, operation with voltages up to 40V, high efficiency, or protection from over-temperature, or open LED
circuit conditions.
Typical applications include MR16/MR11 LED spot lights, LED street lights, parabolic aluminized reflector (PAR)
LED lights, and other general purpose industrial and consumer LED applications.
Figure 3.1, Figure 3.2, Figure 3.3, and Figure 3.4 demonstrate basic application circuits for the four options for
controlling output current described in section 2.
