Functional Safety PMICs
Two-Channel Synchronous Boost/Buck/Buck-Boost Controller with SPI Interface
A81850
The A81850 is a versatile two-channel synchronous DC/DC controller engineered for complex power supply designs. Its architecture supports boost, buck, or buck-boost topologies, providing the flexibility to regulate a wide range of input-to-output voltage conditions with a single IC. An integrated SPI interface enables detailed configuration and real-time diagnostic fault reporting for robust system control and monitoring. For higher power requirements, multiple A81850 devices can be configured in an array to scale the output current capability.
