... Functional Description The MIC2289 is a constant frequency, PWM current mode boost regulator. The block diagram is shown above. The MIC2289 is composed of an oscillator, slope compensation ramp generator, current amplifier, g amplifier, PWM generator, 500mA bipolar output transistor, and Schottky rectifier diode. The oscillator generates a 1.2MHz clock. The clock’ ...

... Open-Circuit Protection If the LEDs are disconnected from the circuit case an LED fails open, the sense resistor will pull the FB pin to ground. This will cause the MIC2289 to switch with a high duty-cycle, resulting in output overvoltage. This may cause the SW pin voltage to exceed its maximum voltage rating, possibly damaging the IC and the external components ...
