MP28300 – ULTRA-LOW IQ STEP-DOWN CONVERTER PCB Layout Guidelines
Efficient PCB layout of the switching power 1) Place the input capacitor as close to the IC supply and especially the high-switching pins as possible for the high speed step- frequency converter is critical for stable down regulator to provide clean control operation. If the layout is not carefully done, the voltage for the chip. regulator could show poor line or load 2) Place the CIN1 close to VIN1 and GND to regulation and stability issues. For best results, absorb noise. refer to Figure 2 and follow the guidelines below.
