(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.

Application Notes

PT6680 Series

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

V_a= Adjusted output voltage

5. Adjustments to the output voltage may place additional

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

must comply with the following requirements.
