Description
The PT3400 Excalibur power modules
are a series of 35-W rated DC/DC converters
housed in a low-profile space-saving copper
case. Fully isolated for telecom applications,
the series includes a number of standard volt-
ages, including 1.0 VDC. Other applications
include industrial, high-end computing, and
other distributed power applications that
require input-to-output isolation.
PT3400 modules incorporate a feature
that simplifies the design of multiple voltage
power supplies in DSP and ASIC applications.
Using the SEQ control pin, the output voltage
of two PT3400 modules in a power supply
system can be made to self sequence at power-
up. Other features include output voltage
adjust, over-current protection, input under-
voltage lockout, and a differential remote
sense to compensate for any voltage drop
between the converter and load.
