ADI LTC1149CS#TRPBF

降压降压最高 48V

Overview

The LTC ®1149 series is a family of synchronous stepdown switching regulator controllers featuring automatic Burst ModeTM operation to maintain high efficiencies at low output currents. These devices drive external complementary power MOSFETs at switching frequencies up to 250kHz using a constant off-time current-mode architecture.

■ Operation to 48V Input Voltage■ Ultrahigh Efficiency: Up to 95%■ Current Mode Operation for Excellent Line and Load Transient Response■ High Efficiency Maintained over Wide Current Range■ Logic-Controlled Micropower Shutdown■ Short-Circuit Protection■ Very Low Dropout Operation: 100% Duty Cycle■ Synchronous FET Switching for High Efficiency■ Adaptive Nonoverlap Gate Drives■ Available in 16-Pin Narrow SO Package
