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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3
