The MIC2289C-34YD6-TR from Microchip Technology is a Pulse Width Modulated (PWM) boost switching regulator designed for efficient constant-current white LED driver applications. This device features an internal Schottky diode and three levels of output overvoltage protection (OVP), enabling a compact DC/DC solution that requires minimal external components.
Key electrical specifications include a wide input voltage range of 2.5V to 10V and an output voltage capability of up to 34V with OVP. It operates at a constant frequency of 1.2MHz, which helps reduce external component sizes and minimizes noise and input ripple. The regulator offers over 500mA of switch current and features a low feedback voltage of 95mV to optimize efficiency by reducing power dissipation in the current set resistor.
This LED driver provides excellent regulation, with less than 1% line and load regulation. It also includes features such as <1µA shutdown current, overtemperature protection, and UVLO (undervoltage lockout). The device is available in a low-profile 6-pin Thin SOT-23 package, suitable for surface mounting.
The MIC2289C-34YD6-TR is well-suited for various backlighting applications, including cell phones, PDAs, GPS systems, digital cameras, MP3 players, and IP phones, as well as LED flashlights and constant current power supplies.
