PT6680_14 Datasheet, PDF (1/7 Pages) Texas Instruments – Single Device: 5A Output
PT6680 Series
5 Amp 18-36V Input
Integrated Switching Regulator
SLTS098
(Revised 6/30/2000)
• Single Device: 5A Output
• Input Voltage Range: 18V to 36V
• Adjustable Output Voltage
• 80% Efficiency
• Remote Sense Capability
• Standby Function
The PT6680 series is a new addi-
tion to Power Trends’ line of 24V bus
Integrated Switching Regulators (ISRs).
Designed for general purpose indus-
trial applications requiring as much as
36V input and 5A of output current,
the PT6680 is packaged in a 14-Pin
SIP (Single In-line Package) and is
available in a surface-mount configu-
ration.
Only two external capacitors are
required for proper operation. Please
note that this product does not include
short circuit protection.

Notes (1) The 560µF electrolytic input capacitor must be rated for 1.5Arms ripple current. Both an input and output capacitor is required for proper operation.
(2) The ISR will operate down to no load with reduced specifications.
(3) Consult the SOA curves or contact the factory to determine the appropriate derating.
