Automotive 125°C operation 36V input 600mA
Step-down Synchronous Rectification
Requirements of an automotive camera module
- Changed from
VGA to 1 or 2 MP
- Must be blended into the vehicle’s appearance
Reduces the footprint of a switching regulator
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 (3.0mm x 2.0mm).
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.
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.
