    The PT6620 series is a new addition
    to Power Trends’ line of 12V bus Inte-
    grated 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 con-
    figuration.
    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 330F(output) and 330F(input) electrolytic capacitors for proper operation in all applications.
