APW7065 APW7065KE SOP8

The APW7065 uses fixed 300kHz switching frequency,
voltage mode, and synchronous PWM controller which
drives dual N-channel MOSFETs. The device integrates
the control, monitoring and protection functions into a
single package, provides one controlled power output
with under-voltage and over-current protections.
The APW7065 provides excellent regulation for output load
variation. The internal 0.8V temperature-compensated
reference voltage is designed to meet the requirement of
low output voltage applications. An built-in digital soft-
start with fixed soft-start interval prevents the output volt-
age from overshoot as well as limiting the input current.
The APW7065 with excellent protection functions: POR,
OCP and UVP. The Power-On-Reset (POR) circuit can
monitor VCC supply voltage exceeds its threshold volt-
age while the controller is running, and a built-in digital
soft-start provides output with controlled voltage rise. The
Over-Current Protection (OCP) monitors the output cur-
rent by using the voltage drop across the lower MOSFET’s
RDS(ON), comparing with internal VOCP (0.29V), when the
output current reaches the trip point, the controller will
run the soft-start function until the fault events are
removed. The Under-Voltage Protection (UVP) monitors
the voltage of FB pin for short-circuit protection, when the
VFB is less than 50% of VREF (0.4V), the controller will shut-
down the IC directly.
