DESCRIPTION:
The MSK 5040 series are high efficiency, 4 amp, surface mount switching regulators. The output voltage is
configured for 1.9V, 2.5V, 3.3V or 5.0V internally with a tolerance of 1% at 1.5 amps. The operating frequency of
the MSK 5040 is 300KHz and is internally set. An external "soft start" capacitor allows the user to control how
quickly the output comes up to regulation voltage after the application of an input. An extremely low quiescent
current of typically less than 2.5mA and nearly 95% operating efficiency keep the total internal power dissipation of
the MSK 5040 down to an absolute minimum.
