降压稳压器

面向隔离式降压调节器设计而优化的A6986I和L6986I DC/DC转换器拥有宽泛的输入电压范围和低静态电流，确保能在最高5W的汽车和工业应用中稳健运行且有效节能。

对于需要一个稳定非隔离型初级电压和一个或多个隔离型次级电压的系统，隔离式降压拓扑极大地减少了物料清单。

除此之外，还有评估板帮助设计人员构建和验证自己的设计。

意法半导体的微型ST1PS01、ST1PS02和ST1PS03降压转换器的静态电流仅为500 nA，针对电池供电和能量收集应用特别提供数字电压选择功能，能够在各种工作条件下实现高效率。

由于采用集成式电源开关和补偿网络，新一代降压转换器仅需几个外部组件即可工作。

三种产品都可使用评估板，以支持开发人员的设计工作。

Housed in a HTSSOP16-package, the A7987 is a 3 A step-down switching regulator with a wide input-voltage range, making it suitable for 24 V battery-powered applications.

Specifically recommended to design flexible and robust solutions, the A7987 also offers a set of additional functionalities including adjustable current limit, synchronization with a 180° phase shift, and power sequencing.

These key features ensure flexible and stable performance when several voltage rails are powered up in automotive applications such as body infotainment and telematics.

In the quest for higher efficiency and compact form factor in their DC-DC supply designs, engineers now have a few more allies: the L6985F, L6986F and L6986 step-down DC-DC regulators with synchronous rectification and an output current of 0.5 A, 1,5 A and 2 A respectively.
Based on a peak current mode architecture with a p-channel power MOSFET, they feature a selectable low-consumption-mode (LCM burst mode) to increase efficiency at light load, and a low-noise-mode (LNM with fixed PWM switching frequency) for noise-sensitive designs.

An easy-to-use evaluation board (STEVAL-ISA156V1) based on the L6986 regulator is available to help you configure and evaluate application parameters so you can reach higher efficiency, higher power density and lower standby power designs.
