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 Va (min) and Va (max).

Va -Vo
Adjust Up:
An increase in the output voltage is obtained by
- 0.1
R2
adding a resistor R2, between pin 11 (Vo adjust) and pins 2, 6, or
7 (GND).
Adjust Down: Add a resistor (R1), between pin 11 (Vo adjust)
and pins 8, 9 or 10 (V1out).
Where:
Vo = Original output voltage
Va = 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 Vo adjust to either GND or
Vo . Any capacitance added to the Vo 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 V1out and –V2out, the revised maximum
output current must be reduced to the equivalent of 6Watts
and 3Watts respectively. i.e.
