General Description
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.

PLEASE NOTE!

These parts came to us as part of a lot of surplus stock from a large ‘Mispec’ type Co. and have been kept in storage for some time, we have therefore classified them as ‘new other’, they are however pristine, stored with us sealed in original packaging, the photographs are representative of their general condition, being of some of our actual stock, and, as with all our products they come with a full guarantee.
