45V, 1.6MHz, 600mA Step-Down Converter CXSD61071 is a wide input range With a fixed switching frequency of 1.6MHz, this current mode PWM controlled converter allows the use of small external component

   产品概述 返回TOPAdo嘉泰姆

The CXSD61071 is a wide input range, highefficiency, and high frequency DC-to-DC stepdown switching regulator, capable of delivering up to 0.6A of output current. With a fixed switching frequency of 1.6MHz, this current mode PWM controlled converter allows the use of small external components, such as ceramic input and output caps, as well as small inductors. Including cold crank and double battery jumpstarts, the minimum input voltage may be as low as 4.5V and the maximum up to 45V, with even higher transient voltages. With these high input voltages, linear regulators cannot be used for high supply currents without overheating the regulator. Instead, high efficiency switching regulators such as CXSD61071 must be used to minimize thermal dissipation. CXSD61071 is available SOT23-6 Packages
