Product Selector Guide
• Single Device: 5A Output
• Input Voltage Range: 9V to 28V
• Adjustable Output Voltage
• 80% Efficiency
• Remote Sense Capability
• Standby Function
The PT6650 series is a new addi-
tion to Power Trends’ 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.
