MIC3223 High Power Boost LED Driver

The MIC3223 is a constant current boost LED driver capable of driving a series string of high power LEDs. The MIC3223 can be used in general lighting, bulb replacement, garden pathway lighting and other solid state illumination applications. The MIC3223 is a peak current mode control PWM boost regul.

MIC3223 Features

* an enable pin for a low power shutdown state. The MIC3223 is a very robust LED driver and offers the following protection features: over voltage protection (OVP), thermal shutdown, switch current limiting and under voltage lockout (UVLO). The MIC3223 is offered in a low profile exposed pad 16-pin TS
