NCP5252

NCP5252 Buck Regulator - Integrated, Synchronous, Light Load Efficiency 2.0 A, 1.0 MHz NCP5252 is a synchronous buck regulator with integrated high-side and low-side MOSFETs. The device is capable of operating from a 5 V or 12 V supply and can output a voltage down to 0.6 V. The switching frequency is adjustable from 333 kHz up to 1.0 MHz and has the ability to provide skip mode for light load efficiency. NCP5252 protection features include Under Voltage Lock Out (UVLO), Over Voltage Protection (OVP), Cycle-by-Cycle Current Protection (OCP) and Thermal Shutdown. The part is packaged in a 3x3 mm QFN-16. Features 1% Accuracy 0.6 V Reference VCC Voltage 4.5 V to 13.2 V Adjustable Output Voltage Range: 0.6 V to 5.0 V Transient Response Enhancement (TRE) Feature.
