Analog Front-End (AFE) With Digital Monitoring and Configuration

View All Parametrics

Combine the Speed of an Analog Controller with the Flexibility of a Digital Microcontroller

Our AFE products, formerly known as Digitally Enhanced Power Analog (DEPA) products, feature analog control loops with digital oversight using analog references, amplifiers and Pulse-Width Modulation (PWM) generators to regulate an output, while configuring, monitoring, measuring and dynamically adjusting that performance with an embedded microcontroller (MCU). This allows the system to report telemetry; make operating adjustments on the fly and respond to faults with customized, application-specific code. Without this added integration, flexible robust designs could require separate chips to regulate the output, adjust the regulator operation, measure the results and communicate the information outside the system. These AFE controllers make it easy to create compact, efficient and flexible power supplies.
