1 What is AECM control? | AECM is a control topology based on a fixed-frequency modulation with
emulated current information for the loop control. |
2 PCM | PCM is a popular fixed-frequency control topology for DC/DC converters given
its overload protection, accuracy and ease of compensation. |
3 D-CAP2 control scheme | The D-CAP2 control scheme is a variation of adaptive COT control with an
emulated ramp-generator circuit integrated inside the IC. |
4 AECM control benefits | AECM control topology can help engineers simplify EMI filter design with
fixed frequency and supports wide- output, large-duty-cycle applications
with good load-transient performance |
5 How AECM control works | AECM control offers mode-detection block to identify whether the DC/DC
converter is in PWM mode or PFM mode. Its integrated oscillator generates
the fixed clock in PWM mode, enables on-time generator and adjusts DC gain
to achieve high bandwidth. |
