MIC3232 - Constant Current Boost Controller

Download the MIC3232 datasheet PDF. This datasheet also covers the MIC3230 variant, as both devices belong to the same constant current boost controller family and are provided as variant models within a single manufacturer datasheet.

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.

Key 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 and1MHz. Setting the switching frequency provides the mechanism by which a design can be optimized for efficiency (performance) and size of the ext.

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. 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%.
