The PT3400 ExcaliburTM 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 voltages, 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 powerup. Other features include output voltage adjust, over-current protection, input undervoltage lockout, and a differential remote sense to compensate for any voltage drop between the converter and load.
