General Description
The APW7078 is a single PWM, step-up DC-DC control-
ler with low operating voltage application integrating soft-
start and short circuit detection function. The oscillator
switching frequency on chip can be operated by terminat-
ing OSC pin to connect capacitor and resistor for adjust-
able operating frequency. Soft-start is adjusted with the
external capacitor, which sets the input current ramp.
Besides, the external compensation FB pin will apply the
flexibility in the dynamic loop status, which allows using
small and low equivalent series resistance (ESR) ce-
ramic output capacitors.

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).
