The industry’s smallest package

The automotive-quality 36V input, synchronous rectification and 125℃ operation switching regulator (DC-DC converter) , which can be connected to the battery directly, adopt the industry’s smallest package (2.46mm x 1.96mm).

In addition, our lineup also includes a gull wing package when mountability is a prime concern.

They can be used in a broad range of applications not only in automotive camera modules where compact size is essential, but also in Electronic Control Units (ECU) and sensors.

There is no need for a large capacitor

Slope compensation circuits and phase compensation circuits in the S-19902/3 Series have been optimized to provide a high transient response.

The external high output capacitors used to compensate for overshoot and undershoot have been downsized, which has also contributed to lowering costs.

S-19902_ripple

External parts to reduce ripple are not required

The S-19903 Series employs a proprietary low-ripple circuit that ensures low ripple without any external parts.

It achieves 9mVp-p across the full load current range including even during PFM control, which is especially prone to ripple.

There is no need to add external parts as a countermeasure to ripple.
