ON NCP1597AMNTWG

降压降压4V5.5V2A

Overview

The NCP1597A 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 NCP1597A 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 2.0 A. 

Features • Input Voltage Range: from 4.0 V to 5.5 V • Internal 140 m High−Side Switching P−Channel MOSFET and 90 m Low−Side N−Channel MOSFET • Fixed 1 MHz Switching Frequency • Cycle−by−Cycle Current Limiting • Overtemperature Protection • Internal Soft−Start • Start−up with Pre−Biased Output Load • Adjustable Output Voltage Down to 0.8 V • Power Saving Mode During Light Load • These are Pb−Free Devices Applications • DSP Power • Hard Disk Drivers • Computer Peripherals • Home Audio • Set−Top Boxes • Networking Equipment • LCD TV • Wireless and DSL/Cable Modem • USB Power Devices
