The PT6620 series is a new addition
to Power Trends’ line of 12V bus Inte-
grated Switching Regulators (ISRs).
Designed for stand-alone operation in
applications requiring as much as 6A of
output current, the PT6620 is packaged
in a 14-Pin SIP (Single In-line Package)
and is available in a surface-mount con-
figuration.
Only two external capacitors are
required for proper operation. Please
note that this product does not include
short circuit protection.
