The PT6600 series is a new addi-
tion to the Power Trends鈥?high
performance family of 14-Pin SIP
(Single In-line Package) Integrated
Switching Regulators (ISRs), designed
for stand alone operation in applications
requiring as much as 9A of output cur-
rent (10A with a side heat tab).
Only two external capacitors are
required for proper operation. Please
note that this product does not include
short circuit protection.

* ISR will operate down to no load with reduced specifications.
** See SOA curves
Note:
The PT6600 Series requires two 330碌F electrolytic capacitors (input and output) for proper operation in all applications.
