The CLOZD loop controller is a low-cost digital control chip developed for simplicity, robustness and versatility.
The 80W convertor has 12V input with output adjustable from 1 to 11V on a through-hole PCB measuring 9.1 x 3.8cm.
Key performance parameters include 92% efficiency and 12mV RMS ripple at 156kHz switching frequency.
Micro has 20MHz clock and performs PID control updates every 25.6us for 200us step-load recovery.
Design processes, firmware optimisation, robust practices, and evaluation methods for digital power control are illustrated through proven techniques.
Concepts are universal to other devices and applications enabling effective trades prior to detailed design in a variety of industries.
The kit includes blank PCB, programmed chip, and documentation with schematic, parts list, description, Spice model, and protected source code.
