General Description
The APW7074 is a voltage mode synchronous PWM con-
troller with fixed 300kHz switching frequency, which driv-
ers dual N-channel MOSFETs. The device integrates the
controling, monitoring, and protecting functions into a
single package, which provides a controlled power out-
put with under-voltage and over-current protections.
The APW7074 provides excellent regulation for out-
put load variation. The internal 0.8V temperature-com-
pensated reference voltage is designed for the require-
ments of low output voltage applications.
The APW7074 has excellent protection functions: POR,
OCP, and UVP. The Power-On-Reset (POR) circuit can
monitor the VCC, EN, and OCSET voltage to make sure
the supply voltage exceeds their threshold voltage
while the controller is running. The Over-Current Pro-
