5V to 12V/15V 9W DUAL OUTPUT

INTEGRATED SWITCHING REGULATOR

Revised 5/15/98

• Dual Outputs:

Regulator (ISR) designed for use in +5 volt

+12V @ 0.5A

-12V @ 0.25A

• Wide Input Voltage Range:

• 85% Efficiency

• Adjustable Output Voltage

• Laser-trimmed Output Voltage

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.

The Power Trends’ PT5060 Series

is a dual output Integrated Switching

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

also be calculated using the following formulae.

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_a(min) and V_a(max).

3.65 (V_a– 2.5 )

(V_o– V_a)

(R1)

- 0.1

kΩ

9.125

V_a-V_o

Adjust Up:

An increase in the output voltage is obtained by

- 0.1

adding a resistor R2, between pin 11 (V_oadjust) and pins 2, 6, or

7 (GND).

Adjust Down: Add a resistor (R1), between pin 11 (V_oadjust)

and pins 8, 9 or 10 (V1_out).

Where:

V_o= Original output voltage

V_a= Adjusted output voltage

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

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

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_oadjust to either GND or

V_o. Any capacitance added to the V_oadjust 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_outand –V2_out, the revised maximum

output current must be reduced to the equivalent of 6Watts

and 3Watts respectively. i.e.
