The PT6620 series is a new addition to Power Trends’ line of 12V bus Integrated Switching Regulators (ISRs).

Designed for stand-alone operation in 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 configuration.

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 - 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.
