Power supply turning on sequence
① Please turn on EN with Vcc≧4.5V or more after impressing Vcc.
② Please fix the potential of DRLIN and THM before turning on EN.
③ A soft start operates at the same time as turning on EN, and the switching is output.
④ After turning on VCC, the order is not related to other input when inputting external PWM from VTH.)
※It leads to the destruction of IC and external parts because it doesn't error output according to an external
constant of adjacent pin 24pin SW terminal, 25pin OUTH terminal, 26pin CS terminal and 27pin BOOT
terminal.
