General Description
The MIC4576 is a series of easy to use fixed and adjustable BiCMOS step-down (buck) switch-mode voltage regulators. The 200kHz MIC4576 duplicates the pinout and function of the 52kHz LM2576. The higher switching frequency may allow up to a 2:1 reduction in output filter inductor size.
The MIC4576 is available in 3.3V, and 5V fixed output versions or a 1.23V to 33V adjustable output version. Both versions are capable of driving a 3A load with excellent line and load regulation.
The feedback voltage is guaranteed to ±2 tolerance for adjustable versions, and the output voltage is guaranteed to ±3 for fixed versions, within specified voltages and load conditions. The oscillator frequency is guaranteed to ±10.
In shutdown mode, the regulator draws less than 200μA standby current. The regulator performs cycle-by-cycle current limiting and thermal shutdown for protection under fault conditions.
This series of simple switch-mode regulators requires a minimum number of external components and can operate using a standard series of inductors. Frequency compensation is provided internally.
The MIC4576 is available in TO-220 (T) and TO-263 (U) packages for the industrial temperature range.
