ML4866
LAYOUT
For proper performance, all components should be placed
as close to the ML4866 as possible. Particular attention
should be paid to minimize the length of the connections
between the COMP and V
REF
pins to GND. Also avoid
bringing these traces and the associated components
close to V
L
.
It is always recommended that a 10µF or greater
capacitor be connected to V
IN
of the ML4866. A 33µF
tantalum capacitor and 100nF film or ceramic capacitor
is recommended when powering the ML4866 from
Lithium or Alkaline cells.
Ground and power planes must be large enough to carry
the current the converter has been designed to supply.
