MIL-M-38510-702 Microcircuits, Linear, Regulating Pulse Width Modulators, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, regulating, 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3
