TPS54383,, TPS54386
SLUS774B – AUGUST 2007 – REVISED OCTOBER 2007
The value of the resistor is calculated using a ratio of impedances to match the ratio of ESR zero frequency to
the desired zero frequency.
where:
• f
ESR(zero) is the ESR zero frequency of the output capacitor.
• f
ZERO(desired) is the desired frequency of the zero added to the feedback. This frequency should be placed
between 20 kHz and 60 kHz to ensure good loop stability.
