PT4494N [Texas Instruments]

The PT4474 is a programmable isolated DC/DC converter module with an input voltage range of 18V to 36V and a programmable output voltage range of 4.6V to 5.7V. It provides up to 20A of output current and can be boosted to 40A with two PT4494 booster modules. Key features include 90% efficiency, 1500 VDC isolation, operation over a case temperature range of -40°C to +115°C, and built-in protections (over-current, over-temperature, over-voltage). The module also features differential remote sense, on/off inhibit control, and comes in space-saving, solderable copper case packages (Vertical, Horizontal, SMD) with safety approvals (UL 60950, CSA 22.2 950, VDE EN60950 pending).
