onsemi Switching Regulator Surface Mount 3.85 V / 4.1 V DC Output Voltage, 380 mW, 9 Pins, SOIC Package NCP1616A2DR2G

onsemi NCP1616A2DR2G is a surface mount switching regulator delivering precise output voltages of 3.85 V and 4.1 V DC with a power rating of 380 mW. Housed in a 9-pin SOIC package measuring 5 mm by 4 mm by 1.75 mm, it supports high voltage input up to 700 V DC and operates reliably across a temperature range from -40°C to 150°C. This regulator features a high voltage start-up circuit and current controlled frequency foldback to optimize performance with a broad variety of MOSFETs and power levels.

The integrated input filter capacitor discharge circuitry and dynamic response enhancer improve transient response and startup speed, enhancing efficiency and reliability. Soft overvoltage protection with drive capability between -500 mA and +800 mA safeguards against faults, while AC line brownout detection adds further robustness. It achieves improved efficiency at light load conditions and minimizes acoustic noise and component stress during overvoltage faults.

This switching regulator is ideally suited for industrial and commercial off-line power supplies, LED lighting drivers and power supplies, lighting ballasts, and high-performance adapter applications. Its compact SOIC package and surface mount design make it suitable for modern PCB assemblies requiring reliable voltage regulation at high voltages.
