LM2595

stabilizing circuit

2A 150KHZ DC switching voltage

Characteristic

Summary

 The input voltage range is 4.5V to 40V.

LM2595 is a PWM DC-DC stabilized

power converter with fixed frequency of

150KHz. It has the characteristics of 2A

output current driving capability, high

efficiency, low ripple, high linear regulation

rate and load regulation rate. The chip

adopts PWM modulation mode to adjust the

linear range of duty cycle from 0 to 100%.

LM2595 has a built-in fixed frequency

 The regulated output has 3.3V, 5V, 12V and output

adjustable versions, and the adjustable range of the

output adjustable version is 1.23V to 37v.

 The duty ratio can be adjusted from 0% to 100%

 The minimum saturation pressure drop is 1.5V

 150KHz fixed working frequency

oscillator and frequency compensation

module, which is simple to use and requires

only a few external components. In addition,

the chip also has built-in functions such as

enabling with hysteresis function, over-

 2A Fixed current output capability

 ON-OFF hysteresis switch function

 Built-in over-temperature protection and over-

temperature

protection,

over-current

current protection

protection and stimulation over-current

protection. When the secondary overcurrent

protection occurs, the chip's built-in

frequency reduction function reduces the

working frequency from 150KHz to 50KHz.

 Built-in frequency compensation function

 High working efficiency, linear adjustment rate and

load adjustment rate
