PT4241A [Texas Instruments]

The PT4240 series are 10W isolated DC/DC converters housed in an ultra-low profile (8mm) solderable copper case. They feature an input voltage range of 18V to 36V and preset output voltages from 1.2V to 13.2V, with 1500 VDC isolation and operation over -40°C to +85°C temperature range. Key capabilities include Remote On/Off control, undervoltage lockout, output current limit, short-circuit protection, and safety approvals (UL 60950, CSA 22.2 60950). The modules support both horizontal and vertical pin configurations, including surface mount, and are suitable for low-power digital/analog circuits like DSPs and microcontrollers.
