PT6620 Series

6 Amp 12V Input

Integrated Switching Regulator

SLTS036B

(Revised 9/20/2000)

•

Single Device: 6A Output

Input Voltage Range: 9V to 16V

Adjustable Output Voltage

83% Efficiency

Remote Sense Capability

Standby Function

signed for stand-alone operation in

applications requiring as much as 6A

of output current. The PT6620 se-

ries is packaged in Power Trends’

standard 14-Pin SIP (Single In-line

Package), which is available in either

a vertical or horizontal configura-

tion. Two electrolytic capacitors are

required for proper operation.

Over-Temperature Protection

The PT6620 series is a line of 12V

bus Integrated Switching Regulators

(ISRs). These regulators are de-

Please note that this product does

not include short circuit protection.
