MIC3230/1/2

Constant Current Boost Controller for

Driving High Power LEDs

General Description

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.

Bringing the Power to Light™

Features

• 6V to 45V input supply range

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.

• Capable of driving up to 70W

• Ultra low EMI via dithering on the MIC3231

• Programmable LED drive current

• Feedback voltage = 250mV ±3%

• Programmable switching frequency (MIC3230/1) or

400kHz fixed frequency operation (MIC3232)

• PWM Dimming and separate enable shutdown

• Frequency synchronization with other MIC3230s

• Protection features:

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.

Over Voltage Protection (OVP)

Over temperature protection

Under-voltage Lock-out (UVLO)

• Packages:

An external resistor sets the adjustable switching

frequency of the MIC3230/1. The switching frequency can

be between 100kHz and1MHz. 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 lock-out (UVLO).

16-pin TSSOP

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.

• –40°C to +125°C junction temperature range

The MIC3232 is a 400kHz fixed frequency device offered

in a small 10-pin MSOP package. The MIC3230/1 are

offered in both the EPAD 16-pin TSSOP package and the

12-pin 3mm × 3mm MLF^®package.

Applications

• Street lighting

• Solid state lighting

• General illumination

• Architectural lighting

• Constant current power supplies
