■ Product Introduction
LM2674 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, built-in overcurrent protection,
power switch control and other circuits. It can drive
500MA 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
Product features
● Built in overtemperature shutdown function
● Built in overcurrent protection function
● Internal integrated efficient power switch
● Good linearity and load adjustment capability
● ON/OFF pin with hysteresis function
● TTL shutdown capability
● high efficiency
● Simple periphery
● Wide input voltage range: 7V~40V
● Fixed output voltage: 3.3V, 5V, 12V, etc
● Adjustable output voltage range: 1.21V~37V
(adjustable)
● High precision output: ± 2
● Fixed switching frequency: 260 kHz
● Maximum output current capacity: 500mA
● Minimum linear drop voltage drop: 1.5V
● Package form: SOP-8
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.
