(*1) ISEN pin voltage measured at start of GATE pin switching.

(*2) Indicates VSINE pin voltage at which OFF TIME 6μs switching becomes possible.

(*3) VDD pin voltage measured when GATE pin=L occurs.

(*4) VDD pin voltage measured when GATE pin=H occurs.

(*5) Indicates internal supply current when “H” level is input into EN/DIM pin and all circuits are activated. (When not switching.)

(*6) Indicates internal supply current when “L” level is input into EN/DIM pin and the switching circuit is stopped.

(*7) Indicates the current that discharges the capacitance between the VDD and GND pins at VOVP.

(*8) Please refer to P.7 “CIRCUIT④”.

(*9) May not be fixed at 6μs when UVLO is detected or during DIM signal control.

(*10) When the current limit voltage VLIM is exceeded, off time is extended to about 140μs to prevent element damage.

For details, refer to the operation description.

(*11) To protect the IC from thermal destruction, thermal shutdown activates when the chip temperature reaches 150oC and forcibly sets the GATE

pin voltage to “L”. When the chip temperature falls to 130

oC, operation resumes.

(*12) Time from attainment of EN/DIM “L” voltage until GATE pin=L.

(*13) Time from attainment of EN/DIM “H” voltage until GATE pin=H.
