Module description


XL4015 has excellent linear regulation rate and load regulation rate chip integrated over-current protection, over-temperature protection, short-circuit protection and other reliability modules. This product adopts XL4015 switch voltage regulator chip, integrated inductor, high-quality aluminum electrolytic capacitor, peak input up to 36V, output 1.25 ~ 32V continuously adjustable.

The XL4015 is a 180 kHz fixed frequency PWM step-down DC/DC converter. It can drive a 5A load with high efficiency, low ripple and excellent linear and load adjustment rates.
A minimum number of external components are required, and the regulator is simple to use, including internal frequency compensation and a fixed frequency oscillator. PWM control circuit can linearly adjust duty cycle from O to 100%. Built-in overcurrent protection function, when triggered by short circuit protection function, the operating frequency is reduced from 180 kHz to 48 kHz.
Built-in internal compensation blocks to reduce the number of external components
Chip characteristics:
8V-36V Wide Voltage Input
The output can be adjusted from 1.25V to 32V.
Maximum duty cycle 100%
Minimum reduction of 0.3V
Fixed switching frequency of 180 kHz
5A Constant Output Current Capability
Internal Optimized Power MOSFET
Efficiency can be as high as 96%.
note:The above chip features are only used as user selection, not equivalent to module features.

Precautions for using the module


(1) The module belongs to the step-down type module, the input voltage needs to be greater than the output of more than 1V to stabilize the output.

(2) The heating of the module is mainly determined by the input and output voltage difference and the load current. Please choose and use the power module reasonably. Generally, you need to reserve 30% of the surplus.

(3) The module generates heat during use, please purchasers to enhance heat dissipation according to the actual situation, when there is a large load; heat sinks, air cooling, etc. can be added appropriately.

(4) When using capacitive or inductive loads, the instantaneous current of the load cannot be too large, otherwise the module may be damaged.


Frequently asked questions

Q: Why the output voltage of the module cannot be greater than the input voltage?

A: The module is a step-down module and cannot be boosted; the maximum output voltage will be less than the input voltage of about 0.3V.
