PD-97731 ASAP SERIES HIGH RELIABILITY HYBRID DC-DC CONVERTERS 28V Input, Single and Dual Output 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 H element evaluation as required by MIL-PRF-38534. These two grades are fully tested and operate over the full military temperature range without derating of output power. A commercial grade is also available. Variations in electrical, mechanical and screening requirements can be accommodated. Extensive computer simulation using complex modeling allows design modifications to be examined.

Parameter guaranteed and measured during line and load regulation tests. Bandwidth guaranteed by design. Tested for 20 KHz to 2.0 MHz. Capacitive load may be any value from 0 to the maximum limit without compromising dc performance. A capacitive load in excess of the maximum limit will not disturb loop stability but may interfere with the operation of the load fault detection circuitry, appearing as a short circuit during turn-on. Parameter shall be tested as part of design characterization and after design or process changes. An overload is that condition of load in excess of rated load but less than that necessary to trigger the short circuit protection and is the condition of maximum power dissipation. Load step transition time between 2.0 and 10 microseconds. Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1.0 percent of VOUT at 50% load. Input step transition time between 2.0 and 10 microseconds. Turn-on delay time measurement is for either a step application of power at the input or the removal of a ground signal from the inhibit pin (pin 2) while power is applied to the input. www.irf.com 3 ASAP Series Absolute Maximum Ratings Input Voltage Power Output Soldering Temperature Temperature Range -0.5V to 50V Continous, 80V for 1 second Internally limited 300°C for 10 seconds Operating -55°C to +125°C Case Storage -65°C to +150°C TEST Conditions -55° ≤ TC ≤+125°C VIN = 28V dc ±5% CL = 0 unless otherwise specified Output voltage IOUT = 0 1, 2 Output current Load regulation Min Max Min Max Min Max 1 ±4.95 ±5.05 ±11.88 ±12.12 ±14.85 ±15.15 2, 3 ±4.90 ±5.10 ±11.76 ±12.24 ±14.70 ±15.30 VIN = 15, 28, and 50 Vdc either output 1, 2, 3 240 960 100 400 80 320 mA V 100 200 200 mV PP VIN = 15, 28, and 50 Vdc IOUT = 0, 50%, 100% IMAX 1, 2, 3 ±50 ±50 ±50 mV 4 VIN = 15, 28, and 50 Vdc IOUT = 0, 50%, 100% IMAX 1, 2, 3 ±50 ±50 ±50 mV 20% to 80% load change 1, 2, 3 15 8.0 8.0 % IOUT = 0 Pin 5 connected to pin 7 1, 2, 3 12 12 12 60 60 60 5 IOUT = 0 Pin5 open 3, 4 Input ripple current 4 Isolation IOUT = IMAX 1, 2, 3 IOUT = IMAX 1, 3 70 71 71 2 66 68 68 1 100 100 100 4 200 Input to output or any pin to case (except pin 8) at 500 Vdc, Tc = +25° C 6, 7 No effect on dc performance, total for both outputs Power dissipation load fault 4 Switching frequency Output response to step transient load changes Overload IOUT = IMAX IOUT = 50% Recovery time, step transient load changes IOUT 4, 9, 10 IOUT Output response transient step line 4, 7, 11 changes VIN IMAX 4, 7, 10, 11 Turn on overshoot 4 4, 12 Load fault recovery 1, 2, 3 Ù 100% I 4, 5, 6 MAX Ù 50% I = 50% Ù 100% I = 0 Ù 50% I = 15 Ù 50Vdc,I = IOUT = 0 Recovery time transient step line changes 8 100 Short circuit 4, 9 Turn on delay Unit 1, 2, 3 Input current Capacitive load ASAP2815D/XX VIN = 15, 28 and 50 Vdc Cross regulation Efficiency ASAP2812D/XX 4 Output ripple voltage Line regulation 3, 4 ASAP2805D/XX Group A Subgroups 4, 5, 6 MAX MAX Ù 50Vdc, I MΩ 200 200 µF 5.0 5.0 5.0 W 2.0 2.0 2.0 500 600 500 600 -400 +400 -400 +400 -400 +400 -800 +800 -800 +800 -800 +800 -750 mA PP % 600 4, 5, 6 4, 5, 6 100 500 MAX OUT 100 mA 100 100 100 2000 2000 2000 +750 - 750 +750 -750 KHz mV pk µs +750 mV pk 4, 5, 6 1200 1200 1200 µs IOUT = 0 and IMAX 4, 5, 6 600 600 600 mV pk IOUT = 0 and IMAX 4, 5, 6 25 25 25 ms 4, 5, 6 25 25 25 ms VIN = 15 IMAX OUT = 7 For Notes to Specifications, refer to page 5 4 www.irf.com ASAP Series Notes to Specifications for Table on page 4 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12.
