The MIC3289-16YD6-TR is a PWM boost-switching regulator designed by Microchip Technology for constant-current white LED driver applications. This device features an internal Schottky diode, enabling an efficient DC/DC solution with minimal external components. It supports a wide input voltage range from 2.5V to 6.5V, making it suitable for battery-powered devices.
The regulator operates at a constant frequency of 1.2MHz, which helps reduce external component sizes and minimize switching noise. It offers a switch current capability of up to 500mA and provides ±5% LED current accuracy. The device also includes features like over-voltage protection and over-temperature protection.
Designed for ease of use, the MIC3289-16YD6-TR allows for digital control of dimming over 16 logarithmic steps via a single wire. It is available in a compact TSOT-23-6 package, suitable for surface mounting, and operates within a junction temperature range of -40°C to 125°C.
Key applications include LED backlighting for cell phones, PDAs, digital cameras, and MP3 players, as well as LED flashlights and constant current power supplies.
