The MIC3230/1/2 are constant current boost switching controllers specifically designed to power one or more strings of high power LEDs. The MIC3230/1/2 have an input voltage range from 6V to 45V and are ideal for a variety of solid state lighting applications.
The MIC3230/1/2 utilizes an external power device which offers a cost conscious solution for high power LED applications. The powerful drive circuitry can deliver up to 70W to the LED system. Power consumption has been minimized through the implementation of a 250mV feedback voltage reference providing an accuracy of ±3%. The MIC323x family is dimmable via a pulse width modulated (PWM) input signal and also features an enable pin for low power shutdown.
Multiple MIC3230 ICs can be synchronized to a common operating frequency. The clocks of these synchronized devices can be used together in order to help reduce noise and errors in a system.
An external resistor sets the adjustable switching frequency of the MIC3230/1. The switching frequency can be between 100kHz and 1MHz. Setting the switching frequency provides the mechanism by which a design can be optimized for efficiency (performance) and size of the external components (cost). The MIC323x family of LED drivers also offer the following protection features: Over voltage protection (OVP), thermal shutdown and under voltage lockout (UVLO).
The MIC3231 offers a dither feature to assist in the reduction of EMI. This is particularly useful in sensitive EMI applications, and provides for a reduction or emissions by approximately 10dB.
The MIC3232 is a 400kHz fixed frequency device offered in a small MSOP-10 package. The MIC3230/1 are offered in ePad TSSOP-16 package.
