General Description
The APW7062B is a voltage mode and synchronous PWM
controller which drives dual N-Channel MOSFETs. It inte-
grates the control, monitoring, and protection functions
into a single package, provides one controlled power
outputs with under-voltage and over-current protection.
APW7062B provides excellent regulation for output load
variation. An internal 0.8V temperature-compensated
reference voltage is designed to meet the requirement of
low output voltage applications. It includes a 200kHz free-
running triangle-wave oscillator that is adjustable from
70kHz to 800kHz.
The power-on-reset (POR) circuit monitors the VCC, EN,
and OCSET input voltage to start-up or shutdown the IC.
The over-current protection (OCP) monitors the output
current by using the voltage drop across the upper
MOSFET’s RDS(ON), eliminating the need for a current sens-
ing resistor. The under-voltage protection (UVP) moni-
tors the voltage of the FB pin for short-circuit protection.
The over-current protection trip cycle the soft-start func-
tion until the fault events be removed. Under-voltage pro-
tection will shutdown the IC directly.
