NCP1593A, NCP1593B
1 MHz, 3 A Synchronous
Buck Regulator
The NCP1593 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 NCP1593 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 0.6 V and is able to supply up to 3 A of load current.

MARKING
DIAGRAMS
The NCP1593 includes an internally fixed switching frequency
(F SW ), and an internal soft ? start to limit inrush current. Other features
include cycle ? by ? cycle current limiting, 100% duty cycle operation,
short ? circuit protection, power saving mode and thermal shutdown.
