ZTP7195C

ZTP7195C 5A Peak Output Current, 18V, 500KHz, Synchronous Step-Down DC/DC Converter FEATURES ● ● ● ● ● ● ● ● ● ● ● DESCRIPTION 4.5V to 18V input voltage Output adjustable from 0.6V to 15V Peak output current up to 5A Integrated 70mΩ/30mΩ power MOSFET switches Shutdown current 3μA typical Efficiency up to 95% Fixed frequency 500KHz Internal soft start Over current protection and Hiccup Over temperature protection RoHS Compliant and 100% Lead (Pb) Free The ZTP7195C is a high-frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. It offers a very compact solution to achieve a 5A peak output current over a wide input supply range, with excellent load and line regulation. The ZTP7195C has synchronous-mode operation for higher efficiency over the output current-load range. Current-mode operation provides fast transient response and eases loop stabilization. Protection features include over-current protection and thermal shutdown. The ZTP7195C requires a minimal number of readily available, standard external components and is available in a space-saving TSOT23-6L package.
