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.
