The MIC3289 is a PWM boost-switching regulator designed for constant-current white LED driver applications. It features an internal Schottky diode, enabling an efficient DC/DC solution with minimal external components. The device operates at a constant frequency of 1.2MHz, which helps reduce external component sizes and switching noise.
Key features include a wide input voltage range of 2.5V to 6.5V, suitable for battery-powered devices. It offers a low shutdown current of 1µA to preserve battery life. The regulator provides a 1.2A switch current and a feedback voltage of 250mV for high efficiency and accuracy. It supports 16 steps of logarithmic dimming control via a single wire.
The MIC3289 is available in an 8-MLF® (2x2mm) package and is designed for surface mounting. Its operating junction temperature range is -40°C to +125°C.
Applications include LED backlighting for cell phones, PDAs, digital cameras, and LED flashlights.
