ABLIC Launches the S-19932/3 Series, an Automotive Step-down Switching Regulator in an Ultra-compact Package

- The HSNT-6 (2025) package shrinks the size of an automotive camera module enabling the installation of multiple, high-performance modules to meet market needs -

ABLIC Inc. (President: Nobumasa Ishiai, head office: Chiba City, Chiba Prefecture; hereinafter “ABLIC”) today launched the S-19932/3 Series of step-down switching regulators for automotive use.

The S-19932/3 Series is a synchronous rectification step-down switching regulator for automotive use featuring 18V input (22V rating), 600mA output current, 125℃ operation, and an oscillation frequency of 2.2MHz, in a compact 2.46 x 1.96 x t0.5mm HSNT-6 (2025) package. The output voltage can be set to any value over the range, 1V to 12V, using an external resistor.

It is also PPAP (Production Part Approval Process) capable and is designed to qualify for the AEC(*)-Q100 Grade 1 (* Automotive Electronics Council) standard for automotive ICs.

Because automotive safety standards have become more stringent, more vehicles tend to come with multiple camera modules installed. The reason is that camera modules are not only used as view cameras, but are also increasingly expected to act as sensing cameras for vehicle control.
The high resolution and high power consumption of a sensing camera mean that integrating the ISP (Image Signal Processor) with the camera increases its size. The ISP has therefore been moved to the ECU (*1) to downsize each high-resolution camera module for better blending with the vehicle's overall appearance. In addition, sensing cameras require redundant power ICs for functional safety.

The new S-19932/3 Series launched today is the ideal product, compact enough to meet market needs for multiple automotive camera modules, high-resolution, and power IC redundancy.
