MIC3223 - High Power Boost LED Driver

General Description

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.

Key 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 TSSOP package. Data sheets and support documentation can be found on Micrel’s web site at: www. micrel. com. Features.

MIC3223 www.DataSheet4U.com High Power Boost LED Driver with Integrated FET General Description 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 regulator and the 4.5V and 20V operating input voltage range allows multiple applications from a 5V or a 12V bus. The MIC3223 implements a fixed internal 1MHz switching frequency to allow for a reduction in the design footprint size. Power consumption has been minimized through the implementation of a 200mV feedback voltage that provides an accuracy of ±5%.
