The Micrel Inc. MIC2287CYD5TR is a constant-current, white LED driver IC designed for boost (step-up) applications. It features a switching frequency of 1.2MHz, which allows for smaller external components, reducing board space. The device accepts an input voltage range from 2.5V to 10V and can provide an output voltage of up to 34V with a maximum output current of 500mA. This capability allows it to drive a series string of up to eight white LEDs.
The driver utilizes a constant frequency PWM control scheme, which helps minimize noise and input ripple compared to variable frequency topologies. The feedback voltage is set to 95mV to optimize efficiency by reducing power dissipation in the current-set resistor. The MIC2287CYD5TR is housed in a TSOT-23-5 surface-mount package.
This LED driver is suitable for applications requiring regulated LED current and brightness control. Its boost topology makes it ideal for systems where the input voltage is lower than the required LED forward voltage.
