XL1583

3A 380KHz 23V Buck DC to DC Converter

Features

General Description

Wide 3.6V to 23V Input Voltage Range

Output Adjustable from 1.222V to 21V

The XL1583 is a 380KHz fixed frequency

PWM buck (step-down) DC/DC converter,

capable of driving a 3A load with high

efficiency, low ripple and excellent line and

load regulation. Requiring a minimum

number of external components, the regulator

is simple to use and include internal

EN pin with hysteresis function

Built in thermal shutdown function

The PWM control circuit is able to adjust the

duty ratio linearly from 0 to 100%. An enable

function, an over current protection function

is built inside. When short protection function

happens, the operation frequency will be

reduced from 380KHz to 80KHz. An internal

compensation block is built in to minimize

external component count.

Supply Voltage Input Pin. XL1583 operates from a 3.6V to 23V

DC voltage. Bypass Vin to GND with a suitably large capacitor

to eliminate noise on the input.

VIN

Power Switch Output Pin (SW). Output is the switch node that

supplies power to the output.

Ground Pin. Care must be taken in layout. This pin should be

placed outside of the Schottky Diode to output capacitor ground

path to prevent switching current spikes from inducing voltage

noise into XL1583.

GND

Feedback Pin (FB). Through an external resistor divider

network, Feedback senses the output voltage and regulates it.

The feedback threshold voltage is 1.222V.

Enable Pin. Drive EN pin low to turn off the device, drive it

high to turn it on. Floating is default high.

Test Circuit and Layout guidelines

Figure5. Standard Test Circuits and Layout Guides

Select R1 to be approximately 2K, use a 1% resistor for best stability.

C1 and CFF are optional; in order to increase stability and reduce the input power line noise, CIN

and C1 must be placed near to VIN and GND;

For output voltages greater than approximately 10V, an additional capacitor CFF is required. The

compensation capacitor is typically between 100 pf and 33 nf, and is wired in parallel with the

output voltage setting resistor, R2. It provides additional stability for high output voltage, low

input-output voltages, and/or very low ESR output capacitors, such as solid tantalum capacitors.

CFF=1/(31*1000*R2); This capacitor type can be ceramic, plastic, silver mica, etc. (Because of

the unstable characteristics of ceramic capacitors made with Z5U material, they are not

recommended.)
