Nisshinbo NC2780 Evaluation Board
Nisshinbo Micro Devices NC2780 Evaluation Board is based on the NC2780 CMOS-based buck switching regulator, which operates with external high-side and low-side NMOSFETs. The NC2780 features a PFM function and achieves high efficiency even at light loads, enabling low system power consumption. The Nisshinbo NC2780 switching frequency can be adjusted from 250kHz to 1MHz using an external resistor.
Features
- Achieves high efficiency at light load by PFM/PWM Auto-switching mode
- Achieves the EMI noise reduction by using a spread spectrum clock generator
- Duty-over maintains the output voltage very stable even when the input voltage drops during cranking, etc
Applications
- Digital appliances such as digital TVs and DVD players
- Office automation equipment such as printers and fax machines
- Constant power for portable communication equipment, cameras and videos
- Constant power source for battery-powered equipment
- Industrial equipment such as FA equipment and smart meters
- Equipment such as surveillance cameras and vending machines used in outdoor or high-temperature environments
- Equipment with self-heating such as motors, lighting, etc
- Primary constant power supply requiring high current such as cluster, IVI, DCM, etc
- Power source for car accessories including car audio equipment, car navigation system
