Single PWM Switching Controller
Features
General Description
Applications
The APW7078 is a single PWM, step-up DC-DC
controller with low operating voltage application
integrating soft-start and short circuit detection
function. And the oscillator switching frequency on chip
can be operated by terminating OSC pin to connect
capacitor and resistor for adjustable operating
frequency. Soft-start is adjusted with external capacitor,
which sets the input current ramp. Besides, the
external compensation FB pin will apply the flexibility in
the dynamic loop status, which allow using small, low
equivalent series resistance (ESR) ceramic output
capacitors.

Notes: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte in plate
termination finish; which are fully compliant with RoHS and compatible with both SnPb and lead-free soldiering
operations. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J STD-020C
for MSL classification at lead-free peak reflow temperature.
