NCP1595

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 0.8 V 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 http://onsemi.com MARKING DIAGRAM 1 DFN6 CASE 506AH XXXXX ALY...
