Description
The PT5060 series of dual-output
Integrated Switching Regulators (ISRs)
provide a complimentary ±12V or ±15V
from a single +5V input. Applications
include systems that require power for
analog interface circuitry, such as D/A
and A/D converters, and Op Amps. The
output voltage can be adjusted with an
external resistor. These ISRs are made
available in a 12-pin single in-line pin
(SIP) package. Note that these modules
are are not short-circuit protected.

Notes:
(1)Do not operate thes negative output rail of these ISRs below the minimum load.
(2)ISRs based on a boost topology are not short-circuit protected.
(3)The inrush current stated is above the normal input current for the associated output load.
(4)See Safe Operating Area curves or consult the factory for the appropriate derating.
