HIP5600EVAL1 S E M I C O N D U C T O R High Voltage DC to DC Evaluation Board for HIP5600 June 1994 Features Description * Operates from 50VDC to 400VDC The HIP5600IS used on the evaluation board is an adjustable 3-terminal positive linear voltage regulator capable of operating up to 400VDC. The Evaluation Board output voltage is adjustable from 1.2VDC to within 50V of the input voltage with two external resistors, RF1 and RF2. The Eval1 Board is configured to provide 15VDC output from a high voltage DC input (such as rectified AC). A zener diode can be used to replace RF2 if improved accuracy is required. The HIP5600 high voltage linear regulator is capable of sourcing 1mA to 10mA. For short periods of time, it can also provide 40mA peak (typical). * Output Voltage Adjustable (Preset to 15VDC) * Output Current to 10mA at 400VDC Input * HIP5600IS UL Recognized * Adjustable DC Output Voltage 1.2VDC to VIN - 50V * Internal Thermal Shutdown Protection * Internal Over Current Protection * Fused to Protect Board when Improperly Connected Applications * Switch Mode Power Supply Start-Up * Electronically Commutated Motor Housekeeping Supply Protection within the HIP5600 is provided by the on chip thermal shutdown and output current limiting circuitry. The HIP5600 has a unique advantage over other high voltage linear regulators due to its ability to withstand input to output voltages as high as 400V(peak), a condition that could exist under output short circuit conditions. The HIP5600 Electrical specifications are found in Datasheet File Number 3270, immediately available via AnswerFAX (407) 724-3818. * Power Supply for Simple Industrial/Commercial/ Consumer Equipment Controls * Battery Bank Voltage Conversion CAUTION: This product does not provide isolation from AC line. All protection circuitry remains fully functional even if the adjustment terminal is disconnected. However, if this happens the output voltage will approach the input voltage. For applications requiring AC input operation, HIP5600EVAL2 and HIP5600EVAL3 evaluation boards are available. Ordering Information PART NUMBER All HIP5600 Evaluation Boards can be reconfigured to operate with DC (50VDC to 400VDC) or AC (80VRMS to 280VRMS) input voltages. See the appropriate datasheet parts list for component configuration and usage.
