Measure pin7 (pulse out) current for using
current probe.
Increase DC voltage for pin7 (FB IN) through
resistance (100 W), pin7 pulse is made to
output. pin7 DC voltage is upped, and
measure pulse highest level voltage and
increase DC voltage (V6) when pin7 pulse
duty is began to become short. i7 pt is
calculated by bottom type.
I7pt = (pulse highest level voltage - V6 DC
voltage) /100 W
Increase DC voltage for pin4 (FB IN) (early
value is 2.0 V) pin7 pulse is made to output.
Pin4 DC voltage is upped, and measure pin4
voltage when pin7 pulse disappears. (Vth4H)
And Pin4 DC voltage is lowered, and measure
pin4 voltage when pin7 pulse appears.(Vth4L)
Pin4 (FB IN) = GND. Confirm pin7 (pulse out)
pulse is output.
Pin5 (OCL) connect outside power supply.
Pin5 DC voltage is upped, and measure pin5
voltage when pulse disappears.
Pin4 (FB IN) = GND
Confirm pin7 (pulse out) pulse is output.
Pin1 (Vcc) DC voltage is upped, and measure
Vcc voltage when pulse
disappears.(V1OVLO)
Pin4 (FB IN) = GND
Confirm pin7 (pulse out) pulse is output.
Pin3 (standby SW) connect outside power
supply.
Pin3 DC voltage is upped (early value is 0 V),
and measure pin3 voltage when pulse
disappears.
Pin4 (FB IN) connect outside power supply
(3.5 V).
Measure pin4 current.
