11.1 Connecting the IC in an application
A 33 kΩ resistor must be connected between pin IREF and GND. The tolerance of this
resistor adds to any current related tolerances of the IC, including f
components can be connected to pin IREF.
The tolerance and temperature dependency of the capacitor connected between pin CF
and GND will add to the tolerance on f
A Small decoupling capacitor (about 100 pF) is recommended on pin IFB close to the IC.
Normal sized decoupling capacitors (about 10 nF) are recommended on pins DIM and
EOL.
The capacitors at pins CF, CPT, FSHB and VDD should also be placed close to the IC.
A capacitor between pin CIFB and GND of at least 470 pF is needed for stability of the low
switching frequency.
A capacitor between pin VDD and GND of at least 10 nF is needed for stability of the
internal VDD voltage clamp. However, for reliable operation of the IC a low ESR type of at
least 470 nF is recommended.
A capacitor between pin FSHB and SHHB is needed to supply the high-side driver. The
recommended value for this capacitor is
A series resistor of at least 1 kΩ is recommended on pin SLHB.
