Pin4 (FB IN) = GND
Confirm pin7 (pulse out) pulse is output.
Vcc voltage is lowered, and measure V
voltage when pin7 output pulse
disappears.(VUL)
And Vcc voltage is upped, and measure V
voltage when pin7 output pulse
appears.(VUH)
Pin4 (FB IN) = GND
Input voltage Vcc < 5.0 V
(= pin7 pulse is not outputted)
And Vcc voltage is upped (V
Measure source current through V
Pin4 (FB IN) = GND
Confirm pin7 (pulse out) pulse is output.
Measure pulse period, look for frequency.
(F
Above condition, measure pulse rise time
:pulse amplitude 10% to 90% (TRPF)
Above condition, measure pulse fall time
:pulse amplitude 10% to 90% (TSPF)
Above condition, measure pulse Max. voltage.
(VOPMX)
Above condition, measure pulse Min. voltage.
