PT6640 Series

24W 12V Input Positive to Negative

Voltage Converter

SLTS037A

(Revised 6/30/2000)

The PT6640 series is a positive

input to negative output line of

Integrated Switching Regulators

(ISRs). Designed for general purpose

applications, the PT6640 series deliv-

ers a negative output voltage at up

to 24W. The PT6640 is packaged in

a 14-Pin SIP (Single In-line Package)

and is available in a surface-mount

configuration.
