release time:2023-11-01Author source:SlkorBrowse:6337

Today, we will introduce the LM2596S-5.0 3A 150KHZ DC switching voltage stabilizing circuit.


Description

● LM2596/LM2596HV is a fixed frequency PWM DCDC voltage stabilizing power converter with fixed frequency of 150KHz. With the 3A output current driving ability, it has characteristics such as high efficiency, low ripple wave, high linear adjustment rate and load regulation. With the PWM modulation mode, the chip can adjust the linear ranges of the duty ratio of 0-100%. 

● LM2596/LM2596HV has a built-in fixed frequency oscillator and a frequency compensation module, withsimple use, and only a small number of external components and parts are needed. In addition, the chip has built-in functions such as enabling, over-temperature protection, over-current protection and stimulation over-current protection with the hysteresis function. In condition of secondary over-current protection, the built-in down-conversion function can reduce the working frequency from 150KHz to 50KHz.


Features

● Input voltage ranges from 4.5V to 40V, 60V for HV model.

● The voltage stabilizing output has 3.3V, 5V, 12V and output adjustable version, and the adjustable ranges of the output adjustable version are from 1.23V to 37V, 57V for the HV model;

● The adjustable ranges of the duty ratio: 0~100%.

● Minimum saturation voltage drop: 1.5V 150KHz fixed working frequency

● 3A fixed current output capacity.

● ON OFF hysteresis switch function.

● Built-in over-temperature protection and over-current protection.

● Built-in frequency compensation function.

● High working efficiency, linear adjustment rate and load adjustment rate.


Applications
