Frequently Asked Questions
What limits the output current capability of a PowerSoC?
The two main limiting factors are the built-in over-current protection (OCP) and over-temperature protection (OTP).
How does OTP affect performance in different conditions?
Exceeding the OTP threshold triggers a soft-off mode until ambient temperature drops below a second threshold, preventing reactivation.
If I need to operate at high current, what should I check?
Refer to the thermal derating plot (Load current versus ambient temperatures) to determine maximum achievable output current for your desired Vout and ambient temp.
What is the recommended supply voltage range for operation?
The PVIN supply voltage has a specified range of 4.5V minimum to 16V maximum.
