Overview

The IM2403SA is a compact, 2W isolated DC-DC converter designed to provide a regulated 3.3V output from a wide 4:1 input voltage range of 9V to 36V. Housed in a space-saving SIP9 plastic package, it features 1.5kVDC isolation and integrated short-circuit protection for robust power distribution in commercial and industrial systems.

Why Choose This Part

The wide 4:1 input range allows the module to handle both 12V and 24V nominal systems with ease, reducing inventory requirements. Its SIP9 footprint saves significant PCB area compared to DIP modules, while the inclusion of a Remote On/Off pin facilitates low-power standby modes and sequenced power-up.

Applications

Isolated Logic Power
Providing a stable 3.3V rail for microcontrollers and sensors in systems where ground loops or electrical noise must be mitigated.
Industrial Communications
Powering isolated RS-485 or CAN bus transceivers that require 3.3V while operating from a 24V industrial bus.
Distributed Power Architectures
Used as a localized regulator to convert wide-range intermediate bus voltages down to logic levels at the point of load.

Getting Started

When integrating this module, ensure a minimum clearance around the SIP9 package for cooling, as it is rated for operation up to 100 degrees Celsius. Utilize the Remote On/Off pin (Pin 3) to control the output state via a logic-level signal, and place a low-ESR capacitor near the input pins to minimize EMI in sensitive applications.
