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.
