APW7165A 7165A SOP8 SMD

توضیحات

The APW7165 is a voltage mode, fixed 300kHz-switching
frequency, and synchronous buck controller. The
APW7165 allows wide input voltage that is either a single
5~12V or two supply voltages for various applications. A
power-on-reset (POR) circuit monitors the VCC supply
voltage to prevent wrong logic controls. A built-in digital
soft-start circuit prevents the output voltages from overshoot as well as limits the input current. An internal 0.8V
temperature-compensated reference voltage with high
accuracy is designed to meet the requirement of low output voltage applications. The APW7165 provides excellent output voltage regulations against load current
variation.
The controller’s over-current protection monitors the output current by using the voltage drop across the RDS(ON) of
low-side MOSFET, eliminating the need for a current sensing resistor that features high efficiency and low cost.
The APW7165 also integrates over-voltage protection
(OVP) and under-voltage protection circuit which monitors the FB voltage to prevent the PWM output from over
and under voltage.
The APW7165 is available in a simple SOP-8 package
