MCP1640_13 Datasheet, PDF (17/32 Pages) Microchip Technology – 0.65V START-UP SYNCHRONOUS BOOST REGULATOR WITH TRUE OUTPUT DISCONNECT OR INPUT/OUTPUT BYPASS OPTION

MCP1640/B/C/D
The feedback resistors and feedback signal should be
routed away from the switching node and the switching
current loop. When possible, ground planes and traces
should be used to help shield the feedback signal and
minimize noise and magnetic interference.
