NCP1599MNTWG Datasheet, PDF (1/15 Pages) ON Semiconductor – 1 MHz, 3 A Synchronous Buck Regulator

NCP1599
1 MHz, 3 A Synchronous
Buck Regulator
The NCP1599 is a fixed 1 MHz, high−output−current, synchronous
PWM converter that integrates a low−resistance, high−side P−channel
MOSFET and a low−side N−channel MOSFET. The NCP1599 utilizes
internally compensated current mode control to provide good transient
response, ease of implementation, and excellent loop stability.
The NCP1599 includes an internally fixed switching frequency
(FSW), and an internal soft−start to limit inrush current.
Other features include cycle−by−cycle current limiting,
short−circuit protection, power saving mode and thermal shutdown.
