Hello
I have two questions about PTH04070.
1.How many Minimum current limit Value?
2.Upon removal of the fault, the output voltage will promptly recover.
How many cycle the output voltage will promptly recover?

Masaya:
1. PTH04070W will function normally under minimum loads.
2. PTH04070W can only operate in Current limit protection (CLP)under the following conditions. It requires minimum input and output capacitance of 47µF ceramic each ,and recommended 47µF polarized capacitor on output bus.
a. In order for CLP to function a1 The inhibit pin must either be open , no external pullup resistor or a open drain FET must be open if used to control Power on.
b. CLP restart and auto recovery is initialed after the current Limit(CLP) detect a short output bus in about 40-100 cycles. The unit automatically restarts in soft power up mode in about 7-10ms after the short is removed .

Masaya-san :
PTH04070W Overcurrent Protection minimum is not defined. However, the OCP typical minimum is 3.8 Amps at 25°C.
