(Revised 6/30/2000)

• Single Device: 5A Output

• Input Voltage Range: 18V to 36V

• Adjustable Output Voltage

• 80% Efficiency

• Remote Sense Capability

• Standby Function

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.

The PT6680 series is a new addi-

tion to Power Trends’ line of 24V bus

Integrated Switching Regulators (ISRs).

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.

Adjusting the Output Voltage of the

PT6680 5Amp 18-36V Bus Converter Series

Figure 1

The output voltage of the Power Trends PT6680 Series

ISRs may be adjusted higher or lower than the factory

trimmed pre-set voltage with the addition of a single

external resistor . Table 1 gives the respective allowable

adjustment range for each model in the series as V_a(min)

and V_a(max).

obtained by adding a resistor R2, between pin 14 (V_oad-

just) and pins 7-10 (GND).

C O M

Adjust Down:

Add a resistor (R1), between pin 14 (V_o

adjust) and pins 11-13 (V_out).

Refer to Figure 1 and Table 2 for both the placement and value

of the required resistor, either (R1) or R2 as appropriate.

The values of (R1) [adjust down], and R2 [adjust up], can

also be calculated using the following formulae.

Notes:

1. Use only a single 1% resistor in either the (R1) or R2

location. Place the resistor as close to the ISR as possible.

2. Never connect capacitors from V_oadjust to either GND,

V_out, or the Remote Sense pin. Any capacitance added to

the V_oadjust pin will affect the stability of the ISR.

3. If the Remote Sense feature is being used, connecting the

resistor (R1) between pin 14 (V_oadjust) and pin 1 (Remote

Sense) can benefit load regulation.

4. For output voltages above 10.0Vdc, the maximum output

current must be limited to 4Adc.

Where: V_o= Original output voltage

limits on the input voltage for the part. The revised limits

must comply with the following requirements.

IMPORTANT NOTICE

Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other

changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest

issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and

complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale

supplied at the time of order acknowledgment.

TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms

and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary

to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily

performed.

TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and

applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide

adequate design and operating safeguards.

TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or

other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information

published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or

endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the

third party, or a license from TI under the patents or other intellectual property of TI.

Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration

and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered

documentation. Information of third parties may be subject to additional restrictions.

Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service

voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.

TI is not responsible or liable for any such statements.

Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements

concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support

that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which

anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause

harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use

of any TI components in safety-critical applications.

In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to

help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and

requirements. Nonetheless, such components are subject to these terms.

No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties

have executed a special agreement specifically governing such use.

Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in

military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components

which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and

regulatory requirements in connection with such use.

TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of

non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
