scope:

This 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.

The device types shall be as follows:

Device type Circuit 01 Current-mode pulse-width modulator controller 02 Current-mode pulse-width modulator controller

The device class shall be the product assurance level as defined in MIL-M-38510.

The case outlines shall be designated as follows:
