For assistance or to order, call (800) 531-5782 PT3300 Series 30 WATT POSITIVE STEP-DOWN INTEGRATED SWITCHING REGULATOR Application Notes Mechanical Outline Product Selector Guide Revised 5/15/98 The PT3300 is a new series of highinput voltage, 30 Watt, non-isolated Integrated Switching Regulators (ISRs) housed in a 19-pin SIP package. The 20 to 60 V input range allows easy integration into many distributed power applications which utilize 24, 28, or 48V bus architechures. The PT3300 series is available with 3.3, 5, 12, or 15V outputs. The output voltage is adjustable from 90 to 110% of nominal with the addition of an external resistor. Other easy to use features include an inhibit function and remote sense which automatically compensates for any voltage drop from the ISR to the load. As with other Power Trends’ products, the PT3300 includes built in current limit, short circuit protection and over-temperature shutdown. The PT3300 requires a 330µF output capacitor for proper o...
