The Power Trends’ PT5060 Series

is a dual output Integrated Switching

Regulator (ISR) designed for use in +5 volt

systems that require low power ±12 or ±15 volt

rails. They can be used to power such applica-

tion circuits as D/A and A/D converters, Op

Amps, and interface logic. Both output voltages

can be easily adjusted with one external resistor.

These ISRs are offered in a low profile 12-pin

SIP package in either vertical or horizontal

through-hole or SMD-configurations.

Please note that this product does not

include short-circuit protection.

More Application Notes

Adjusting the Output Voltage of the

PT5060 Dual Output Boost Converter Series

The dual output voltage of the Power Trends PT5060 Series

ISRs can be adjusted higher or lower than the factory trimmed

pre-set voltage with the addition of a single external resistor.

Table 1 accordingly gives the applicable adjustment range for

each model in the series as V

(min) and V

(max).

Adjust Up:

An increase in the output voltage is obtained by

adding a resistor R2, between pin 11 (V

adjust) and pins 2, 6, or

7 (GND).

Adjust Down:

Add a resistor

(R1)

, between pin 11 (V

adjust)

and pins 8, 9 or 10 (V1

out

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

of the required resistor, either

(R1)

or R2 as appropriate.

Notes:

1. Both the positive and negative voltage outputs from the ISR

are adjusted simultaneously.

2. Use only a single 1% resistor in either the

(R1)

or R2 loca-

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

3. Never connect capacitors from V

adjust to either GND or

. Any capacitance added to the V

adjust pin will affect

the stability of the ISR.

4. An increase in the output voltage must be accompanied by a

corresponding reduction in the specified maximum current

at each output. For V1

out

and –V2

out

, the revised maximum

output current must be reduced to the equivalent of 6Watts

and 3Watts respectively. i.e.

out

(max)

Adc

and

out

(max)

Adc,

where V

is the adjusted output voltage.

5. Adjustments to the output voltage will also limit the maxi-

mum input voltage that can be applied to the ISR. The

maximum input voltage that may be applied is limited to

out

– 1)Vdc or 14Vdc, whichever is less.
