Ordering and Marking Information
Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D for
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).
The APW8822/A/B/C is equipped with accurate sourc-
ing and current-limit, output under-voltage output over-
voltage protections, being perfect for NB applications. A
1.4ms (typ.) digital soft-start can reduce the start-up
current. A soft-stop function actively discharges the
output capacitors by the discharge device. The
APW8822/A/B has individual enable controls for each
PWM channels. Pulling both EN1/2 pin low shuts down
the all of outputs unless LDO3 output. The LDO3 and
LDO5 of APW8822A/C are always on standby power.
The APW8822/A/B/C is available in a TQFN3x3-20
package.
