The OB2225NCP is a switching controller manufactured by On-Bright with a RoHS-compliant SOP-8 package. It is used as a voltage regulator to control the voltage levels in electronic circuits, providing more accurate and efficient voltage regulation than linear regulators while improving power conversion efficiency and reducing power dissipation. It features an adjustable switching frequency up to 1.2 MHz and a wide operating voltage range from 3V-40V, making it suitable for a variety of applications including battery powered systems, LED lighting, DC-DC converters, and high efficiency power supplies. Featuring the industry standard PWM/PFM mode control and a low-noise ripple compensation circuit, it offers improved noise immunity and dynamic response for tight voltage regulation. It also features integrated protection circuits for over-temperature, over-voltage, and under-voltage protection.
