When the difference between the input and the output is small, some cycles may be skipped completely before current maximizes.
EFFI = { ( output voltage x output current ) / ( input voltage x input current) } x 100
On resistance (Ω)= (V
Designed value.
Time until it short-circuits LX1 (LX2 in the side of 2CH) with GND via 1Ωof resistor from an operational state and is set to Lx=0V from
”H” is judged as “H”>V
When temperature is high, a current of approximately 20μA (maximum) may leak.
Current which EN1 and EN2 are measured separately.
Lead current which LX1 and LX2 are measured separately.
