| Abstract |
This paper describes how mixed signal controllers
combining a cheap microcontroller with a simple analogue
circuit can offer high performance digital control for DC/DC
converters. Mixed signal controllers have the same versatility
and performance as DSP controllers if the microcontroller
software is optimized.
Two mixed signal controller designs based on the same 8-bit
microcontroller are compared both theoretically and
experimentally on a typical Point of Load converter. A 16-bit
digital PID controller using lookup tables with a sampling
frequency as high as 200 kHz implemented on the 16 MIPS, 8-bit
ATTiny26 microcontroller is demonstrated. |
