意法半导体的单片式DC-DC开关稳压器具有高达61 V的输入电压能力,降压转换器能够提供高达6 A的输出电流,开关频率高达2.3MHz。


这些 开关电源 嵌入了一套完整的保护功能(过流、过电压、过温),以增加MTBF,减少功率转换所需的外部元件数量.提供了多种封装选项,全都可以实现小型化和高散热性能以满足不同应用的要求。

ST还具有独特且完全隔离、共振的单级直接转换,从48V直接转换到负载点(POL),完全符合Intel VR13和VR12.5规范的CPU/DDR,以及完全可扩展的解决方案,能够管理多达6个交错单元,动态单元脱落和脉冲跳频。

New high-efficiency DC-DC converter with digital output voltage selection and power good pin pushes performance beyond the limits

A miniaturized step-down regulator that draws a quiescent current of only 500 nA, the ST1PS01 is specifically tailored for battery-powered and energy-harvesting applications as it ensures a highly efficient power conversion regardless of the input voltage source and output current being delivered:

  • an input voltage ranging from 1.8 to 5.5 V
  • a minimal set of external components thanks to the integrated power switch, synchronous rectifier, and the embedded compensation network
  • a high efficiency at any load level, 95% at 1 mA output load current

An evaluation board, (STEVAL-1PS01EJR) helps developers quickly understand how to take advantage of the ST1PS01’s high energy efficiency and feature integration.

60 V 300 mA step-down converter with 10uA quiescent current

ST’s new L7983 is a compact synchronous buck converter able to satisfy noise-sensitive applications and maximize efficiency at light load thanks to its Low-noise and Low-consumption modes.

With a wide input-voltage range, the L7983 can operate from 12 and 24 V industrial buses with wide safety margins. It is also suitable for battery-powered applications, industrial fail-safe systems, decentralized intelligent nodes, appliances, robotics and precision-sensing applications that leverage the easy-to-use Low-noise mode.

Power supply and converter solution evaluation boards based on the L7983 are also available
