The PT6610 series is a high per-
formance +5V family of 14-Pin SIP
(Single In-line Package) Integrated
Switching Regulators (ISRs), designed
for stand alone operation in applica-
tions requiring as much as 9A of
output current.
Only two external capacitors are
required for proper operation. Please
note that this product does not include
short circuit protection.
