Figure 5 AW328XX Application Circuit
(Using external OVP threshold by connecting OVLO to R1 and R2）
Notice for Typical Application Circuits:
1.
When the default OVP threshold is used, connect OVLO pin to GND directly or through a 0
Ω resistor.
OVLO pin cannot be left floating.
2.
If R1 and R2 are used to adjust the OVP threshold, in order to speed up the OVP response, R1 + R2 <
100k
Ω is recommended. It is better to use 1% precision resistors to improve the OVP threshold precision.
3.
If
ACOK is not used, it can be left floating, or short to GND.
4.
CIN = 0.1
μF is recommended for typical application, larger CIN is also acceptable. The rated voltage of CIN
should be larger than the TVS maximum clamping voltage, if no TVS is applied and only AW328XX is
used, the rated voltage of CIN should be 50V.
5.
COUT = 1
μF is recommended for typical application, larger COUT is also acceptable. The rated voltage of
COUT should be larger than the OVP threshold. For example, if the OVP threshold is 6.8V, the rated
voltage of COUT should be 10V or higher.
