            S-19914/5 Series Automotive Switching Regulator
                    ABLIC's S-19914/5 series reduce conducted emission to about 1/3, making it an ideal small single chip
    

ABLIC's S-19914 and S-19915 series have a built-in spread spectrum clock generation circuit to reduce conducted and radiated emissions. The circuit spreads the operating frequency range across a wide bandwidth during PWM operation to suppress noise peaks for specific frequency ranges reducing noise to about 1/3 of ABLIC’s conventional products.

The S-19914 and S-19915 series simplify noise countermeasures and contribute to low-noise automotive cameras and electric control units (ECUs). An automotive-grade switching regulator (DC-DC converter) with a 36 V input capable of direct connection to a battery, 1 A output current, and synchronous rectification housed in an HSNT-8(2030).
