PM6681ATR Frequently Asked Questions (FAQ)
-
STMicroelectronics provides a recommended PCB layout in the application note AN2344, which includes guidelines for thermal vias, copper pours, and component placement to ensure optimal thermal performance.
-
The input capacitor values depend on the input voltage, output voltage, and output current. A general guideline is to use a minimum of 10uF ceramic capacitors with a voltage rating of at least 1.5 times the input voltage. Refer to the application note AN2344 for more detailed guidance.
-
The maximum allowed voltage drop across the internal FETs is typically around 1.5V to 2V, depending on the specific application and operating conditions. Exceeding this voltage drop may lead to reduced efficiency, increased heat generation, or even device failure.
-
To ensure the OCP is triggered correctly, make sure to connect the OCP pin to a suitable current sense resistor and configure the OCP threshold according to the application note AN2344. Additionally, ensure that the OCP pin is properly decoupled from the power supply and output voltage.
-
The recommended operating temperature range for the PM6681ATR is -40°C to 150°C, with a maximum junction temperature of 175°C. Operating outside this range may affect the device's performance, reliability, or lifespan.
