MARKING

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 parts are packaged in a 3x3mm QFN-16.
