PT4220 series power modules are a DC/DC converters designed by Texas Instruments, with an ultra-low profile (8mm) solderable copper case, and a number of preset output voltages ranging from 1.3V † up to 12V. They are fully approved for Telecom use and can be used in many other applications that require input-output isolation over an extended temperature range.
The Texas Instruments PT4220 Series consists of 10W low-profile isolated DC/DC converters housed in an ultra-low profile (8mm) solderable copper case. These modules are fully approved for telecom use and designed for applications requiring input-output isolation over an extended temperature range, including DSPs and microcontrollers.
The series includes preset output voltages ranging from 1.2V up to 13.2V with a wide input voltage range of 36V to 75V. Key features include short-circuit protection, output current limiting, remote on/off control via Pin 1, and an under-voltage lockout (UVLO) circuit.
