Description
The PT6620 series is a line of 12-V
input Integrated Switching Regulators
(ISRs). These regulators are designed
for stand-alone operation in applications
requiring as much as 6 A of output
current. The PT6620 series is pack-
aged in a 14-Pin SIP (Single In-line
Package), which is available in either
a vertical or horizontal configura-
tions, including surface mount.

Notes: (1) The PT6620 Series requires a 330 µF(output) and 100 µF(input) electrolytic capacitors for proper operation in all applications.
(2) ISR will operate down to no load with reduced specifications
(3) See safe Operating Area curves or contact the factory for the appropriate derating.
