PT4474C Description

Short technical summary and product information.

The Texas Instruments PT4474C is an isolated DC/DC converter module from the Excalibur series. It accepts an input voltage of 18V to 36V and provides a programmable output voltage from 4.6V to 5.7V at up to 20A of output current, delivering 100W of output power.

 

This module achieves 90% efficiency and provides 1500VDC input-to-output isolation. It includes protection features such as over-current protection (OCP), over-temperature protection (OTP), over-voltage protection (OVP), and under-voltage lockout (UVLO). The module also supports remote on/off control with an active-low enable input.

 

The PT4474C is housed in a 26-SMD surface mount package measuring 91.7mm x 41.1mm x 12.7mm. It operates over an ambient temperature range of -40°C to +85°C. Safety approvals include UL 60950, CSA 22.2 950, and VDE EN60950 (pending).
