The Texas Instruments PT4661C is a dual-output isolated DC/DC converter from the PT4660 Excalibur Series. Designed for telecom central office applications, it operates from a standard -48V supply (36V to 75V input range) and delivers two independently regulated outputs: 5V at 10A and 3.3V at 15A, for a total of 99W. The module offers 1500VDC input-to-output isolation and operates at 88% typical efficiency.
Protection and control features include remote On/Off control, over-current protection (OCP), over-temperature protection (OTP), over-voltage protection (OVP), and under-voltage lockout (UVLO). Dual logic On/Off control supports flexible power sequencing. The module also includes an input differential EMI filter and meets IPC Lead Free 2 standards.
The PT4661C is housed in a 26-SMD surface-mount module measuring 91.7mm x 41.1mm x 12.7mm. It operates over a -40°C to 85°C temperature range (datasheet specifies up to 100°C). Safety approvals include UL1950 and CSA 22.2 950. Suitable for commercial ITE (Information Technology Equipment) applications.
The PT4661C provides a 5V output and a 3.3V output, both independently regulated.
The input voltage range is 36V to 75V DC.
The total output power is 99W.
Yes, it includes over-current protection (OCP) on both outputs.
The PT4661C is available in a 26-SMD surface-mount module.
