The Silergy step-up regulator is designed to operate across a wide input voltage range, ensuring optimal performance in demanding applications. It integrates an internal MOSFET to Streamline device functionality and reduce component size.
3V to 33V input voltage range for versatile applications
Integrates an internal N-channel MOSFET with low RDS(ON) of 120mΩ to minimise losses
Provides a maximum output voltage of 33V for enhanced system flexibility
Features 4A current limit for reliable operation under varying loads
Includes soft-start circuitry to control inrush current at startup
