Overview
NCP1595, NCP1595A, NCP1595C Buck Regulator- Synchronous 1 MHz, 1.
5 A The NCP1595/A/C family are fixed 1 MHz, high−output−current, synchronous PWM converters that integrate a low−resistance, high−side P−channel MOSFET and a low−side N−channel MOSFET.
The NCP1595/A/C utilizes current mode control to provide fast transient response 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 1.
5 A.
The NCP1595/A/C includes an internally fixed switching frequency (FSW), and an internal soft−start to limit inrush currents.
Using the EN pin, shutdown supply current is reduced to 3 mA maximum.
Other features include cycle−by−cycle current limiting, short−circuit protection and thermal shutdown.
Features • Input Voltage Range: from 4.
0 V to 5.
5 V • Internal 140 mW High−Side Switching P−Channel MOSFET and 90 mW Low−Side N−Channel MOSFET • Fixed 1 MHz Switching Frequency • Cycle−by−Cycle Current Limiting • Overtemperature Protection • Internal Soft−Start • Diode Emulation During Light Load (Disabled for NCP1595C) • Hiccup Mode Short−Circuit Protection • Start−up with Pre−Biased Output Load • Adjustable Output Voltage Down to 0.
