The MIC4576 is a series of easy-to-use fixed and
adjustable BiCMOS step-down (buck) switch-mode
voltage regulators. The 200 kHz MIC4576 duplicates
the pinout and function of the 52 kHz 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 200
µA shutdown 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.
