PCB layout

7.1

Recommended

The STP2CMP is a charge pump power device so it requires a proper PCB layout in order

to obtain the necessary stability and optimize line/load regulation and output voltage ripple.

Input, output, and boost capacitors must be as close as possible to their relative pins.The

example of the evaluation board below is shared with the STP4CMP device which is a pin

compatible device with 4 current sources and the same architecture.
