Product Selector Guide

6 AMP 12V INPUT

INTEGRATED SWITCHING REGULATOR

• Single Device: 6A Output

Designed for stand-alone operation in

• Input Voltage Range: 9V to 14V

• Adjustable Output Voltage

• 83% Efficiency

• Remote Sense Capability

• Standby Function

applications requiring as much as 6A of

output current, the PT6620 is packaged

in a 14-Pin SIP (Single In-line Package)

and is available in a surface-mount con-

figuration.

• Over-Temperature Protection

Only two external capacitors are

required for proper operation. Please

note that this product does not include

short circuit protection.

The PT6620 series is a new addition

to Power Trends’ line of 12V bus Inte-

grated Switching Regulators (ISRs).

* ISR will operate down to no load with reduced specifications.

** See SOA curves - Output power is limited to 30W maximum.

Note: The PT6620 Series requires a 330µF(output) and 330µF(input) electrolytic capacitors for proper operation in all applications.
