tive inputs of the error amplifier, raise up to replace the
reference voltage (0.6V typical) until the ramp voltage
reaches the reference voltage.
Short Circuit Protection
For each channel, when the output is shortened to the
ground, the frequency of the oscillator will be reduced to
210kHz. This lower frequency allows the inductor current
to safely discharge, thereby preventing current runaway.
The oscillator’s frequency will gradually increase to its
designed rate when the feedback voltage on the FB again
approaches 0.6V.
Over-Temperature Protection (OTP)
For each channel, the over-temperature circuit limits the
junction temperature of the APW7176. When the junction
temperature exceeds 150oC, a thermal sensor turns off
the power MOSFETs, allowing the channels to cool down.
The thermal sensor allows the converter to start a softstart process and to regulate the output voltage again
after the junction temperature cools by 40οC. The OTP is
designed with a 40οC hysteresis to lower the average

Inductor Selection

Layout Consideration
For all switching power supplies, the layout is an important step in the design; especially at high peak currents
and switching frequencies. If the layout is not carefully
done, the regulator might show noise problems and duty
cycle jitter.
1. The input capacitor should be placed close to the VIN
and GND. Connecting the capacitor and VIN/GND with
short and wide trace without any via holes for good
input voltage filtering. The distance between VIN/GND
t o c a p a c i t o r l e s s t h a n 2 m m r e s p e c t i ve l y i s
recommended.
2. The high current paths (GND1/GND2, IN1/IN2, and SW1/
SW2) should be placed very close to the device with
short, direct and wide traces.
3. To minimize copper trace connections that can inject
noise into the system, the inductor should be placed as
close as possible to the SW pin to minimize the noise
coupling into other circuits.
4. Since the feedback pin and network is a high impedance circuit, the feedback network should be routed
away from the inductor. The feedback pin and feedback
network should be shielded with a ground plane or
trace to minimize noise coupling into this circuit.
5. A star ground connection or ground plane minimizes
ground shifts and noise is recommended.
