MIL-M-38510-126 Microcircuits, Linear, Regulating, Pulse Width Modulator, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, pulse width modulator microcircuits. Two product assurance classes and a choice of case outlines and lead finishes are provided and are reflected in the complete part number. For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3

11 Continuous short circuit limits will be less than indicated test limits.

21 tOSC is the period of the output waveform.

31 Each output transistor shall be tested for all parameters listed.

41 This is a go-no-go test, the limit values are used for input voltages.

51 Each output shall be tested for all parameters listed. VC = 20 V unless otherwise specified.

61 A 2.7 kν pullup resistor is added from the Sync pin to VREF to limit the effects of stray capacitance in automatic test equipment.

71 Each output shall be tested for all parameters listed VC = 15 V unless otherwise specified.

81 Only use the Shutdown pin, not the Sync pin, to deactivate the device.

3.6 Electrical test requirements. Electrical test requirements for each device class shall be the subgroups specified in table II. The electrical tests for each subgroup are described in table III.

3.7 Marking. Marking shall be in accordance with MIL-PRF-38535.

3.8 Microcircuit group assignment. The devices covered by this specification shall be in microcircuit group number 52 (see MIL-PRF-38535, appendix A).
