1 / 7 page 4707 Dey Road Liverpool, N.Y. 13088 M.S.KENNEDY CORP. (315) 701-6751 FEATURES: 5043 HIGH EFFICIENCY, 8 AMP ADJUSTABLE SURFACE MOUNT SWITCHING REGULATOR Up To 93% Efficiency For 5V Operation 8 Amp Output Current 4.5V to 30V Input Range User Adjustable Output Voltage from 1.2V to 5.5V 300KHz Switching Frequency @ 2.5 Amps User Programmable Soft-Start Quiescent Current < 2.5mA User Programmable Current Limit Contact MSK for MIL-PRF-38534 Qualification Status Available with Gull Wing Leads DESCRIPTION: EQUIVALENT SCHEMATIC The MSK 5043 is a high efficiency, 8 amp, surface mount switching regulator. Output voltage is user adjustable through the use of two external resistors or one external potentiometer. Output voltages from 1.2 volts to 5.5 volts are possible. The operating frequency of the MSK 5043 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 93% operating efficiency at 5 volts out, keep the total internal power dissipation of the MSK 5043 down to an absolute minimum.
