Standard External Circuit
*1 C
IN
: Input capacitor (Approx. 47
μ
F)
This capacitor is required if the input line is inductive and in the case of long wiring.
: Output capacitor (47 to 220
μ
F)
: Delay time setting capacitor (0.1
μ
F or more)
Use C
d
to set the delay time (t
DLY
) from when a low V
O
level due to OCP operation is detected until a flag signal is output.
This prevents a rush current from causing malfunction at start.
Approximate calculation: t

When using soft start on V
IN
or if C
IN
has a large capacitance, set t
DLY
long enough for the output voltage to rise sufficiently
Be sure to connect Cd and do not use it for other applications, such as short circuiting Cd.
: Reverse biasing protection diode
This diode is required for protection against reverse biasing of the input and output.
: Set this to limit the inflow current into the FLG terminal to 1mA or less.

Estimating Tj by Temperature Measurement
1. Measuring position: At the root of pin 13
2. Add the thermal resistance "
θ
j-L" between the junction and pin 13 and the Pd product of each channel to the measured temperature.
θ
j-L is as follows
:
