XL4015 Adjustable DC-DC Step-Down Module 5A

Description

XL4015 Adjustable DC- DC Step-Down Module 5A The XL4015 is a fixed frequency PWM buck (step-down) DC/DC converter operating at 180 KHz. It can efficiently drive a 5A load while maintaining low ripple and excellent line and load regulation. Designed for simplicity, it requires a minimal number of external components and includes internal frequency compensation along with a fixed-frequency oscillator. The PWM control circuit adjusts the duty ratio linearly from 0% to 100%. It features built-in overcurrent protection, which reduces the operating frequency from 180 KHz to 48 KHz in the event of a short circuit. Additionally, an internal compensation block is incorporated to minimize the need for external components. Features: High efficiency up to 96%. The built-in thermal shutdown function. Built-in current limit function. In-Built output short protection function. Input reverse polarity protection. Specification: Module properties: non-isolated step-down module ( BUCK ) Rectification: non-synchronous rectifier Input voltage: 4V ~ 38V DC Output voltage: DC 1.25V ~ 32V ( adjustable ) Output current: 0A ~ 5A Output power: 75W ( more than 50W please add heat sink ) Operating Frequency: 180KHz Operating Temperature: -40°C ~ +85°C Load regulation: S(I)≤0.8% Voltage regulation: S(u)≤0.8% Pin Configuration: Pin Name Description IN+ Positive input (Unregulated or Regulated) IN- Negative input (Ground) OUT+ Positive Output (Regulated) OUT- Negative Output (Ground) Applications: DIY Electronics Projects.
