Introduction

AI Translation

The XL4015 is a 180 KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 5A 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 frequency compensation and a fixed-frequency oscillator. The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%. An over current protection function is built inside. When short protection function happens, the operation frequency will be reduced from 180KHz to 48KHz. An internal compensation block is built in to minimize external component count.

Product FAQ

  • 1. What converter topology, internal switch current capacity, and efficiency ratings define the XL4015E1?
    The XL4015E1 is a 180kHz fixed-frequency PWM step-down (buck) DC-DC regulator IC featuring an integrated internal power MOSFET. It is capable of driving up to 5A of output current with high efficiency of up to 96%. The output voltage is externally adjustable from 1.25V to 32V using a feedback resistor divider referenced to the IC's 1.25V feedback voltage.
  • 2. What input voltage boundaries, oscillator characteristics, and control functions govern IC operation?
    The regulator operates from an 8V to 36V DC input voltage and uses a fixed 180kHz switching frequency, allowing the use of relatively compact external inductors and capacitors. The device also supports a TTL shutdown function using external components. When the TTL control input is above 3.3V (and below 7V), the converter shuts down; when it is below 0.8V, normal operation resumes.
  • 3. Which physical footprint, terminal pin assignment, and package dimensions specify the TO-263-5L housing?
    The XL4015E1 is housed in a 5-lead TO263-5L surface-mount package. The package includes a metal back tab internally connected to the SW (switch) node. Pin assignments are Pin 1: GND, Pin 2: FB, Pin 3: SW, Pin 4: VC, and Pin 5: VIN. According to the package drawing, the package has a nominal E dimension of 10.16 mm, a nominal D1 dimension of 8.70 mm, and a 1.70 mm reference lead pitch.
  • 4. What package options and factory packaging are available for the XL4015E1?
    The XL4015E1 is supplied in the TO-263-5L surface-mount package and is compliant with RoHS & HF (Halogen-Free) requirements. Standard factory packaging is tape and reel, with 800 units per reel.
  • 5. What protection features and operating temperature limits apply to the XL4015E1?
    The XL4015E1 incorporates current limit protection, thermal shutdown, and output short-circuit protection. During output short-circuit protection, the operating frequency is reduced from 180kHz to 48kHz. The device supports an operating junction temperature range of -40°C to +125°C and an absolute maximum lead soldering temperature of 260°C (10 seconds).
