AmP Power Components
AnDAPT offers a broad selection of software based proven Power Components for the AmP family, with competitive figures of merit that replace traditional catalog parts/POLs. Power components of various topologies, range from buck, boost, buck-boost, battery chargers, load switches, LDOs to gate drivers, controllers, sequencers and supervisors. Single and multi-phase regulators and controller topologies are also offered. These come complete with a selection of control loop, compensation, control & telemetry choices.

AmP Platform Architecture
The AmP architecture includes three functional groups.
Each Power Block includes a Scalable Integrated MOSFET (SIM) element. The MOSFETs are scalable and segmented with built-in current sense for current-mode or current balancing. Each SIM element supports two fundamental operating modes switched mode or linear mode. Power blocks are externally connected to build a variety of topologies.
The Senser Block provides capabilities to measure voltage or current levels. Senser blocks are used for analog signaling for regulation, protection and telemetry. Every Sensor Block includes the following functions.
Digital Fabric Control and Interface
Each AmP device includes a digital fabric for building control loops, sequencers and interconnectivity for µAnalog elements and power components. The AmP platform's digital fabric includes functions to monitor and control the analog currents, voltages etc..
The implications for the AmP technology are far reaching, and extend well beyond the initial target market: power management for enterprise servers, networking, wireless and PC/Clients.
The platform is a Senser-PID Controller-Actuator appliance with broad applicability beyond power. Using the same basic technology, engineers could conceivably create, almost instantaneously, any type of analog solution—even solutions that do not yet exist.
On a very concrete level, future applications for the technology could include broader on-demand power management, audio amplifiers, RF, stepper motor, senser/actuators for IoT, brushless direct current motor drivers for drones and industrial devices. But on a higher level, the sky is the limit for the applications of adaptive analog.
