The MIC2287C-34YML-TR from Microchip Technology (formerly Micrel) is a 1.2MHz pulse width modulated (PWM) boost switching regulator designed for constant-current white LED driver applications. It supports an input voltage range of 2.5V to 10V and can deliver an output voltage of up to 34V, with a switch current exceeding 500mA. This device is capable of driving a series string of white LEDs, ensuring uniform brightness.
The regulator operates at a constant frequency of 1.2MHz, which allows for smaller external components and reduced board space. It features a low feedback voltage of 95mV to optimize efficiency by minimizing power dissipation in the current-setting resistor. The MIC2287C-34YML-TR includes overvoltage protection (OVP) options, over-temperature protection, and undervoltage lockout (UVLO).
This specific part, MIC2287C-34YML-TR, is supplied in an 8-lead 2mm x 2mm MLF™ package. It is suitable for surface mounting and operates within a junction temperature range of -40°C to +105°C. Applications include backlighting for cell phones, PDAs, GPS systems, digital cameras, MP3 players, and IP phones, as well as LED flashlights.
