Diodes Incorporated recommends a 2-layer or 4-layer PCB with a solid ground plane on the bottom layer to improve thermal performance. The device should be placed near a thermal pad or a heat sink to dissipate heat efficiently.
To ensure stable output voltage regulation, it is recommended to use a high-quality output capacitor with a low ESR (Equivalent Series Resistance) and a sufficient capacitance value (e.g., 10uF or higher). Additionally, the input capacitor should be placed close to the device to reduce noise and ripple.
Although the datasheet specifies a maximum input voltage of 18V, it is recommended to limit the input voltage to 15V to ensure reliable operation and prevent damage to the device.
The PAM2800AABR has built-in overcurrent protection (OCP) and short-circuit protection (SCP). However, it is still recommended to add external protection components, such as a fuse or a current-limiting resistor, to prevent damage to the device and the PCB in case of a fault condition.
Although the datasheet specifies an operating temperature range of -40°C to 85°C, it is recommended to operate the device within a temperature range of 0°C to 70°C for optimal performance and reliability.
