NCP5252
2.0 A, 1.0 MHz Integrated
Synchronous Buck
Regulator with Light Load
Efficiency
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.
