General Description (Cont.)

(typ.) digital soft-start can reduce the start-up current. A

soft-stop function actively discharges the output capaci-

enable controls for PWM channels and LDOs. Pulling

both ENPWM pin and ENLDO pin low shuts down the

whole chip with low quiescent current close to zero.

The APW8811 is available in a TQFN4x4-24A package.

MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen

free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by

weight).
