PT4222C Description

Short technical summary and product information.

The PT4222C is a member of the PT4220 series of isolated DC/DC converters from Texas Instruments. It delivers a regulated 3.3V output at up to 3A, with a total output power of 10W. The module accepts a wide input voltage range of 36V to 75V, with a nominal input of 48V.

 

Key electrical specifications include a typical efficiency of 81% at full load, 1500VDC input-to-output isolation, and low output ripple of 50mVpp. The converter features tight line regulation of ±1mV and load regulation of ±5mV, with a total output voltage variation of ±1.5% typical. Protection features include remote on/off control, overcurrent protection (OCP), short-circuit protection (SCP), and undervoltage lockout (UVLO).

 

The PT4222C is housed in a 10-SMD surface-mount package measuring 50.8mm x 30.2mm x 7.9mm. It is designed for commercial ITE (Information Technology Equipment) applications and operates over a temperature range of -40°C to +85°C.
