PD-97731 ASAP SERIES HIGH RELIABILITY HYBRID DC-DC CONVERTERS Description The ASAP Series of DC-DC converters are high reliability thick film hybrid converters that use flyback topology operating at a nominal frequency of 550KHz. High input to output isolation is achieved through the use of transformers in the flyback power and feedback circuits. The advanced feedback design provides fast loop response for superior line and load transient characteristics and offers greater reliability than devices incorporating optical feedback circuits. This device is designed to meet MIL-STD-704D input requirements offering full performance over a wide 15 to 50 volt input range and output power of up to 6.0 watts. Connecting the inhibit pin (pin 5) to the input common (pin 7) will cause the converter to shut down. It is recommended that the inhibit pin be driven by an open collector device capable of sinking at least 400µA. The open circuit voltage of the inhibit pin is 11.5 ±0.5 volts. These converters are manufactured in a facility fully qualified to MIL-PRF-38534. All processes used to manufacture these converters have been qualified thereby enabling International Rectifier to deliver fully compliant devices. Four standard temperature grades are offered with the screening options. Refer to Screening Level section. The CH grade converters are fully compliant to MIL-PRF-38534 for class H. The HB grade converters are processed with the same screening as the CH grade, but do not have class ...
