Digitally enhanced power controllers

Power Electronics / Power Management
Microchip announced the availability of a new Digitally Enhanced Power Analog (DEPA) controller designed to regulate current and voltage, and monitor temperature. The device improves digital support for battery charging and is ideal for DC-DC conversion in server, consumer, industrial and automotive applications.
The MCP19124/5 handles configurable charging algorithms for any chemistry, with capabilities for cell balancing and supercapacitor charging. Users may develop their own unique charging methods and implement them as well. Any voltage, current, temperature or duration can be used to trigger a transition to a new portion of the charge profile. These devices are also well suited for any DC-DC application requiring tight voltage or current regulation, capable of supporting flyback, boost, SEPIC or Cuk topologies.
The combination of independent voltage and current control loops means that either the current control loop can regulate to a specified target current, or the voltage control loop can regulate to a target voltage. Each analog control loop has a separate feedback network for independent pole-zero placement, and the ability to perform zero-cross detection for quasi-resonant operation.
The device has the ability to dynamically switch from a voltage target to a current target, or vice versa, by switching between the two control loops. The internal architecture ensures this transition is monotonic, without glitching or transient events. This control configuration even allows for pre-positioning of the output voltage at open or no-load conditions, greatly minimising transients when a load is applied.
A full suite of configurable, adjustable performance parameters is provided. These parameters are set in the internal registers of the device (no external components required) and the settings are dynamically adjustable during operation. The MCP19124/5 has an integrated linear regulator, MOSFET drivers, 8-bit PIC microcontroller core, analog-to-digital converter, precision oscillator, and analog control loops for a compact solution.
