Renesas Electronics ISL85014同步降压稳压器
Renesas/Intersil ISL85014同步降压稳压器是高效单片稳压器，输入电源电压范围为3.8V至18V，可提供14A输出电流。ISL85014稳压器集成了高侧低导通电阻和低侧FET，以最大限度地提高效率。ISL85014器件与高达1MHz的外部时钟同步。ISL85014稳压器采用节省空间的15Ld 3.5mm x 3.5mm无铅TQFN封装。应用包括服务器和云基础设施负载点 (POL)、基础设施保护中心 (IPC)、工厂自动化、PLC和存储系统。
The operation frequency of the ISL85014 can be set using the FREQ pin: 600kHz (FREQ = float) and 300kHz (FREQ = GND). The device can also be synchronized to an external clock up to 1MHz.
Both high-side and low-side MOSFET current limit and reverse current limit fully protect the regulator in an overcurrent event. Selectable OCP schemes can fit various applications. Other protections, such as input/output overvoltage and over-temperature, are also integrated into the device and provide required system-level safety in the event of fault conditions.
The ISL85014 is offered in a space-saving 3.5mm x 3.5mm TQFN-15 package with excellent thermal performance and a 0.8mm maximum height.
