Automotive, 125°C Operation,
18 V Input, 600 mA Synchronous Step-Down Switching Regulator

S-19932/3 Series

Switching Regulator for Automotive S-19932/3 Series

Requirements of an automotive camera module


  • Changed from VGA to 1 or 2 MP
     High resolution

  • Must be blended into
    the vehicle’s appearance
     Compact size

  • To achieve high resolution
    and compact size,
      ISP-less
    (Image Signal Processor-less)


Shrinking the size of
camera parts


Reduces the overall footprint
of a switching regulator
by up to 57%.
Contributes both high resolution
and compact size.

The Ultra-small package enables more compact application

The automotive-quality 18V(Absolute Maximum Ratings 22V) input, synchronous rectification and 125℃ operation switching regulator (DC-DC converter) adopt the ultra-small package HSNT-6 (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.

S-19932_3_response

There is no need for a large capacitor

Slope compensation circuits and phase compensation circuits in the S-19932/3 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-19932_3_ripple

External parts to reduce ripple are not required

The S-19933 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.
