However, to have high performance a more sophisticated compensation network is required, especially when MLCC (Multi Layer Ceramic Capacitor) capacitors are used. MLCC capacitors are widely used at the output of low voltage DC/DC converters because of their low equivalent series resistance (ESR) and low equivalent series inductance (ESL).
It should be noted here that the value of the capacitance used in the compensator design must be the small signal value. Ceramic capacitors lose some portion of their capacitance as their biasing voltage increases. The MLCC capacitors which are used in this example have 22μF nominal capacitance.
The ESR of these capacitors is used to help compensate the power supply. Migrating to an externally compensated design actually can provide a smaller overall solution under these conditions. The external compensation allows the designer to optimize the filter inductor and possibly to use smaller ceramic output capacitors.
Smaller capacitors are acceptable for light loads, or in applications where ripple is not a concern. The control-loop architecture developed by Texas Instruments allows the designer to choose the output capacitors and externally compensate the control loop for optimum transient response and loop stability.
MLCC capacitors are widely used at the output of low voltage DC/DC converters because of their low equivalent series resistance (ESR) and low equivalent series inductance (ESL). Low ESL, which results in high resonance frequency, makes the MLCC capacitors desirable at high switching frequencies.
So, step in the miller capacitor. It is used extensively in opamps to ensure that the overall phase change from DC to high frequencies doesn’t reach 180 degrees by the time the open loop gain has fallen below unity. But sometimes I have read that these parasitic capacitances are terrible regarding stability
