Over-Temperature Protection
The PT6600 series is a high per-
formance 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
current.
The PT6600 series will operate
off either a 3.3V or 5V input bus and
requires only two external capacitors
for proper operation. Please note that
this product does not include short
circuit protection.
