Product Introduction
LM2675 series is a DC/DC switching buck converter controlled
by a fixed frequency of 260kHz PWM.It is mainly composed of
internal frequency compensation, fixed frequency oscillator, builtin
overcurrent protection, power switch control and other circuits.
It can drive 1A load with high efficiency, low ripple, good linearity
and load adjustment ability.Only a few external components
are needed to realize the function of DC/DC voltage reduction and
stabilization, which is very simple and practical.PWM control
circuit can adjust the duty cycle from 0 according to the load
To 100% to achieve high work efficiency.It has an external
enabling control opening function, which can realize the
controllable switch between standby and work, making the
application more flexible.
