DESCRIPTION:

The MSK 5045 series are high efficiency, 4 amp, surface mount switching regulators. The output voltage is config-

ured for 2.5V, 3.3V or 5.0V internally with a tolerance of 1% at 1.5 amps. The operating frequency of the MSK 5045

is 300KHz. 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. A low quiescent current and greater than 85% operating efficiency keep the

total internal power dissipation of the MSK 5045 down to an absolute minimum. The input circuitry has been designed

to withstand a very wide range of voltages from less than 12V to as high as 80V. The device is packaged in a hermetic

kovar flatpack for high reliability applications, and is available screened to MIL-PRF-38534 Class H.
