BENCH TEST CIRCUIT
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.

Note 2:
Maximum load current depends on
inductor value and input voltages.
Output ripple depends on filter
capacitor values, ESRs and the
inductor value.

= 0.45 V
@ 100 mA.
Note 5: Regulation not guaranteed
Note 3:
Note 4:
The Bench Test Circuit is 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 I
OUT
on the bench, the converter was loaded until “no pulse
skipping” mode was achieved.
