Digitally Enhanced Power Analog (DEPA) Hybrid Controllers

Microchip DEPA controllers offer the flexibility of digital microcontrollers

Image of Microchip's Digitally Enhanced Power Analog (DEPA) Hybrid ControllersDEPA products from Microchip Technology maintain the fast, efficient analog feedback loop and incorporate an 8-bit PIC® microcontroller. DEPA controllers contain analog control loops with digital oversight using analog references, amplifiers, and pulse-width modulation (PWM) generators to regulate 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. With DEPA, flexible power supplies are easy, compact, and efficient.

Power designers get the elegance and performance of an analog PWM controller with the customizability of a digital MCU. This offers configurability, including the ability to measure and respond to the environment with tailored algorithms, as well as a communication interface for control or diagnostic functions. DEPA products offer more flexibility than any other analog control architecture on the market today. The single-chip solution accepts a high-voltage input (up to 42 V) and regulates a wide output current or voltage range (0.3 V to 16 V without any external components or drivers for the MCP19123). They offer the tight regulation levels, fast transient responses, high gain, and phase margins required in server or telecommunications operation; with the robustness and operating ranges required for automotive applications. Add dynamic operational changes, measurements, and diagnostic reporting capabilities to any application.

Features
  • Measure the environment, including input voltage, output voltage, current, temperature, external reference, or control signals
  • Respond to the environment; dynamically adjust output voltages, currents, limit conditions, or signaling other devices
  • Intelligently handle problems; customize fault, brownout, overvoltage and undervoltage responses to create predictable system behavior
  • Manage system power; sequence start and shutdown throughout a board for robust operation across all operating conditions
  • Communicate using dedicated output pins or digital interfaces with standard or proprietary messaging schemes
Applications
  • AC-DC converters
  • Automotive
  • Battery management
  • DC-AC inverters
  • Embedded and point-of-load conversion
  • Energy storage
  • Lighting
  • Merchant power supplies
