Buck Regulator - Synchronous 1 MHz, 2 A
ON Semiconductor
The NCP1597B 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 NCP1597B utilizes internally compensated current mode control
to provide good transient response
ease of implementation and
excellent loop stability. It regulates input voltages from 4.0 V to 5.5 V
down to an output voltage as low as 0.8 V and is able to supply up to
2 A.
The NCP1597B has features including fixed internal switching
frequency (FSW)
and an internal soft−start to limit inrush current.
Using the EN pin
shutdown supply current is reduced to 3
A
maximum.
Other features include cycle−by−cycle current limiting
short−
circuit protection
power saving mode and thermal shutdown.
