PS2811-1-K-A Details

Renesas provides a recommended PCB layout guide in their application note (AP6111) for the PS2811-1-K-A. It includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
The PS2811-1-K-A has a thermal pad on the bottom side of the package. Renesas recommends using a thermal via or a thermal pad on the PCB to dissipate heat. A thermal interface material (TIM) can also be used to improve heat transfer between the device and the heat sink.
Renesas recommends using a 10uF to 22uF ceramic capacitor with an X7R or X5R dielectric as the input capacitor. The capacitor should be placed as close as possible to the VIN pin to minimize noise and ensure stable operation.
The PS2811-1-K-A has a power-on reset (POR) circuit that ensures the device is properly powered up. To power down the device, Renesas recommends using an external power switch or a voltage regulator with an enable pin to control the power supply.
The maximum allowed voltage on the EN pin is 6V. Exceeding this voltage may damage the device. Renesas recommends using a voltage limiter or a voltage divider to ensure the EN pin voltage does not exceed 6V.
