NCP5252中文资料同步降压稳压器，集成式，2.0 A，1.0 MHz，具有轻型负载高能效数据手册ONSEMI规格书

描述 Description

NCP5252 is a synchronous buck regulator with integrated high-side and low-side MOSFETs.The device is capable of operating from a +5V or +12V supply and can output a voltage down to 0.6V. 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 parts are packaged in a 3x3mm QFN-16.
