S-19954/19955 Step-Down Switching Regulator ICs

ABLIC S-19954/19955 Step-Down Switching Regulator ICs are designed using CMOS process technologies with a built-in Power Good (PG) function. The S-19954 ICs feature PWM control and can be used without interfering with AM radio bands. The S-19955 ICs feature a PWM/PFM switching control, operates with PWM control under heavy load, and automatically switches to PFM control under light load. These ICs operate from 2.7V to 5.5V input voltage range and -40°C to 125°C temperature range. The S-19954/19955 ICs are used in secondary power supply for automotive equipment, camera modules, and constant-voltage power supply for electrical equipment for vehicle interior applications.
