The PT6650 series is a new addi-
tion to Power Trends鈥?line of 24V bus
Integrated Switching Regulators
(ISRs). Designed for general purpose
industrial applications requiring as
much as 5A of output current, the
PT6650 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.
