Above is the Final Test Circuit through which each of the production parts must pass. In this test circuit, the part is tested

against the specification limits in the data sheet (the min. and max. values in the Electrical Characteristics) at room

temperature, and is rejected if the tested values are outside the minimum (min.) and maximum (max.) values.

The Bench Test Circuits shown on the following pages are the circuits used most of the time to measure the typical (typ.)

values in the Electrical Characteristics section, and make the Typical Performance graphs.

Note: In measuring the oscillator frequency and the Max IOUT on the bench, the converter was loaded until “no pulse

skipping” mode was achieved.
