Pin Function

PT3401r = 3.3V/10A (33W)

PT3402r = 2.5V/12A (30W)

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.
