S-19914/5 Series comes with a built-in spread spectrum clock generation circuit to reduce conducted emission and radiated emission.
The circuit spreads the operating frequency range across a wide bandwidth during PWM operation to suppress noise peaks for specific frequency ranges.
This reduces noise to about 1/3 of our conventional products.

S-19914/5 Series simplifies noise countermeasures and contributes to low-noise automotive cameras and ECUs.

An automotive-grade switching regulator (DC-DC converter) with a 36V input capable of direct connection to a battery, 1A output current and synchronous rectification housed in an HSNT-8(2030), the industry’s smallest package*.
Thanks to an ultra-small package and an oscillation frequency of 2.2MHz, the total mounting area is the industry’s smallest.

Our lineup also includes the HTMSOP-8, a gull-wing package, when mountability is a prime concern.

S-19915 Series employs a proprietary low-ripple circuit that ensures low ripple without any external parts.

Other company products with similar functions recommend use of 20µF output capacitors. However, S-19915 Series makes do with output capacitors with half the capacity of 10µF while generating 10mV or less ripple across the full load current range during PFM control as well as PWM control.

S-19915 Series therefore not only shrinks the size of output capacitors, but also lowers costs.
