These multi-output regulators from Analog Devices form part of their power management family. This range of regulators offers complete power solutions and highly integrated power ICs.
These devices enable reliable power solutions for RF, high speed, and precision analogue products, all from a compact package. They are also ideal for FPGAs and processors.
Analog Devices’ multi-output regulators feature I²C control enabling voltage scaling, sequencing and monitoring. With this they are able to improve conversion efficiency.
They combine functions such as:
- Buck
- Boost
- Buck-boost switching regulators
- Battery chargers
- Autonomous backlight control
- Low noise LDO regulators
- Real-time clocks
