MSK5030

ISO-9001 CERTIFIED BY DSCC M.S.KENNEDY CORP. FEATURES: HIGH EFFICIENCY, 4 AMP STEP-DOWN SWITCHING REGULATORS 5030 SERIES 4707 Dey Road Liverpool, N.Y. 13088 Up To 95% Efficiency For 5V Version 4 Amp Output Current 4.5V to 30V Input Range Preset 2.5V, 3.3V or 5.0V Output Versions 300KHz Switching Frequency @ 1 Amp User Programmable Soft-Start Quiescent Current < 0.5mA User Programmable Current Limit (315) 701-6751 MIL-PRF-38534 QUALIFIED DESCRIPTION: The MSK 5030 series are high efficiency, 4 amp, step-down switching regulators. The output voltage is configured for 2.5V, 3.3V or 5.0V internally and the input range is 4.5V to 30V. The operating frequency of the MSK 5030 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 0.5mA and 95% operating efficiency keeps the total internal power dissipation of the MSK 5030 down to an absolute minimum. A surface mount version, MSK 5040, is also available if desired.
