Product overview

XL4015E1 at a glance

XL4015E1 is the tape-and-reel order code for XLSEMI's XL4015 asynchronous buck-converter IC in a five-lead TO263 package. The device uses fixed-frequency PWM regulation and is intended for step-down power conversion. Its headline 5 A capability depends on the input/output conditions, external components, PCB layout and thermal design described by the manufacturer.

Key features

Verified device capabilities

  • Wide 8 V to 36 V operating input range with an adjustable 1.25 V to 32 V output range.
  • Fixed 180 kHz PWM switching frequency and a documented maximum duty cycle of 100%.
  • Integrated power MOSFET plus internal frequency compensation reduces the required external component count.
  • Built-in thermal shutdown, current limiting and output short-circuit protection.
  • Manufacturer reports efficiency up to 96%; measured efficiency depends on the operating point and implementation.

Applications

Where the device is used

  • Step-down power conversion for LCD monitors and LCD televisions.
  • Portable-instrument power supplies.
  • Power rails in telecom and networking equipment.

Ordering information

Exact code and packing

The reviewed order code is XL4015E1 with XL4015E1 top marking in a TO263-5L package.

The manufacturer ordering table specifies RoHS and halogen-free status and 800 units supplied on tape and reel.

Design notes

Use the rating in context

XL4015E1 is the regulator IC, not a completed CC/CV module. A usable converter requires the external inductor, Schottky diode, capacitors and feedback network shown in the application circuit.

Treat 5 A as a conditional device capability rather than a guaranteed continuous current for every board; component selection, copper area, airflow and temperature affect the result.

The datasheet shows an optional external-component circuit for TTL shutdown: above 3.3 V turns the converter off and below 0.8 V turns it on.

Technical and ordering FAQ

Questions buyers ask about XL4015E1

Answers distinguish the IC itself from assembled modules and keep absolute limits separate from normal operating conditions.

Is XL4015E1 an IC or a complete buck-converter module?

It is a bare buck-converter IC. Boards sold as XL4015 modules add external power components and can have different limits, controls and thermal performance.

What input-voltage range does XL4015E1 support?

The manufacturer specifies an 8 V to 36 V operating input range. The 40 V figure in the document is an absolute maximum rating, not the normal operating ceiling.

Can XL4015E1 always deliver 5 A continuously?

No unconditional board-level promise should be made from the headline rating. The datasheet test circuits, input/output ratio, inductor and diode ratings, PCB layout and thermal conditions must all be considered.

What package and packing does the E1 order code use?

The reviewed ordering table identifies TO263-5L and 800 units on tape and reel for XL4015E1.

What is the adjustable output-voltage range?

The manufacturer feature summary states an adjustable output from 1.25 V to 32 V, subject to the input voltage, duty cycle and application design.
