The MIC3289-16YML-TR is a PWM boost-switching regulator optimized for constant-current white LED driver applications, manufactured by Microchip Technology. It features an internal Schottky diode, requiring only four external components for an efficient DC/DC solution. The device supports a single-wire digital interface for 16-step logarithmic dimming control and pre-programming of start-up brightness levels.
Key electrical specifications include a 2.5V to 6.5V input voltage range, 1.2MHz PWM operation, and over 500mA switch current capability. The feedback voltage is a low 250mV, ensuring high efficiency and accuracy for white LED current. It offers ±5% LED current accuracy and a low shutdown current of <1µA.
This LED driver is designed for applications such as backlighting in cell phones, PDAs, digital cameras, and LED flashlights. It operates within a junction temperature range of -40°C to +125°C. The MIC3289-16YML-TR is available in an 8-MLF® (2x2mm) package, suitable for surface mounting.
