ZT7184

ZT7184 3A, 23V, 340kHz, Synchronous Step-Down DC/DC Converter FEATURES ● ● ● ● ● ● ● ● ● ● ● DESCRIPTION The ZT7184 is a 340kHz fixed frequency PWM synchronous step-down regulator. The ZT7184 is operated from 4.75V to 23V, the generated output is adjustable from 0.925V to 20V, and the output current can be up to 3A. The integrated two MOSFET switches is with turn on resistance of 85mΩ. Current mode control provides fast transient response and cycle-by-cycle over current protection. The shutdown current is 1μA typical. Adjustable soft start prevents inrush current at turn on. The ZT7184 is with thermal shutdown. The ZT7184 is available in the SOP-8L package, and it is RoHS compliant and 100% lead (Pb) free. 4.75V to 23V input voltage Output adjustable from 0.925V to 20V Output current up to 3A Integrated 85mΩ power MOSFET switches Shutdown current 1μA typical Efficiency up to 95% 340kHz fixed frequency Programmable soft start Over current protection Over temperature protection RoHS Compliant and 100% Lead (Pb) Free ● ● ● ORDERING INFORMATION PART PACKAGE RoHS Yes ZT7184S SOP-8L(EP) Typical Application Circuit DS-07; Sep. 04, 2009 Copyright © ZillTek Technology Corp.
