The MIC9130 is a current-mode PWM controller that efficiently converts -48V telecom voltages to logic levels. The MIC9130 features a high voltage start-up circuit that allows the device to be connected to input voltages as high as 180V. The high input voltage capability protects the MIC9130 from line transients that are common in telecom systems. It also saves board space and simplifies designs by integrating several external components. The MIC9130 is capable of high speed operation. Typically the MIC9130 can control a sub-25ns pulse width on the gate out pin. its internal oscillator can operate over 2.5MHz, with even higher frequencies available through synchronisation. The high speed operation of the MIC9130 is made safe by the very fast, 34ns response from current sense to output, minimizing power dissipation in a fault condition. The MIC9130 allows for the designs of high efficiency power supplies. It can achieve efficiencies over 90% at high output currents. Its low 1.3mA quiescent current allows high efficiency even at light loads. The MIC9130 has a maximum duty cycle of 50%. For designs requiring a high duty cycle, refer to the MIC9131. The MIC9130 is available in a 16-pin SOP (small-outline package). The rated junction temperature range is from -40°C to +125°C.
