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
”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.
When the difference between the input and the output is small, some cycles may be skipped completely before current maximizes.
PARAMETER
from current limit pulse generating.

If current is further pulled from this state, output voltage will decrease because of P-ch driver ON resistance.
