Logic input
Abnomal condition sensing monitor
It is a pull-up resistor for
Abnomal condition
sensing monitor.
The setting range is
10k‰ to 100k‰
The REG1 voltage (1V) can be
used to set output current.
It can connect to VREF directly
or after divided with resistors.
The setting range (total) is
10k‰ to 100k‰
Please refer to P.7 for details.
It sets the PWM frequency.
The setting range is
100pF to 500pF
Please refer to P.8 for details.
Logic input
It is a resistor to detect output
current
The setting range is
0.1‰ to 1‰
Please refer to P.7 for details.
Each constant setting method for the above circuit diagram example is as follows :
Current LIMIT (100%) set
VREF = 1.0V (when internal regulator output is connected)
ILIMIT = VREF / 5 / RNF resistance
= 1.0V / 5 / 0.47
Ω = 425mA
Chopping frequency setting
Fchop = Ichop / (Cchop × Vt × 2)
= 10
μA/ (220pF × 0.5V × 2) = 45 kHz
No.A1685-11/12
