SG1846J-883B

Overview

The SG1846J-883B is a current mode PWM controller manufactured by Microchip Technology. It features dual sink/source outputs and operates within an input voltage range of 8 to 40V. The device supports both PWM and resonant control topologies, including buck, boost, and push-pull configurations. It is housed in a 16-pin ceramic dual in-line package (CDIP) designed for military-grade reliability. The component functions as a DC-DC switching controller with soft-start capabilities.

Feature Summary

Supports multiple converter topologies including buck, boost, and push-pull
Features dual sink and source output drivers for flexible interface options
Incorporates internal soft-start functionality to manage inrush currents

Applications

Military-grade power supply systems
High-reliability DC-DC conversion circuits
Resonant controller applications

Procurement Notes

Verify the manufacturer origin carefully, as Linfinity Microelectronics and Microsemi also produced this part number under different corporate histories. Confirm the specific suffix indicates the correct package type and temperature rating. Ensure the component meets the required MIL-STD-883B screening levels if specified for your application. Cross-reference the datasheet version to confirm electrical characteristics match your design requirements.

Selection Notes

Select this component when a robust current mode PWM controller is required for high-reliability environments. It is suitable for designs needing dual drive outputs and support for various switching topologies. Consider the ceramic DIP package for superior thermal and mechanical stability compared to plastic variants. Evaluate the 8-40V operating range against your system's power constraints.

Part Context

This component belongs to the SG1846 family of switching controllers. It shares functional similarities with other industry-standard PWM controllers but is distinguished by its military-grade packaging and screening. The part is often associated with legacy aerospace and defense power management systems requiring long-term availability and strict quality standards.
