Description
Description
The XL6009 15W Adjustable Step-Up DC-DC Converter Module is a high-performance, compact boost converter designed to efficiently elevate lower DC voltages to higher, adjustable output levels. Featuring a built-in Enable Pin for remote on/off control, this module is ideal for applications where power management and sequencing are critical.
At the heart of this module is the XL6009E1 chip, a second-generation high-frequency switching regulator from XLSEMI that integrates a high-current 4A MOSFET switch . This advanced design delivers superior performance compared to older LM2577-based modules, with higher efficiency, higher switching frequency, and more compact overall dimensions .
Power Ratings:
-
Natural Cooling: 15W maximum output power
-
With Heatsink: 25W maximum output power
Enable Pin Feature: The module includes an Enable (EN) control pin that allows you to remotely turn the converter on or off without disconnecting the input power. This is particularly useful for:
-
Power sequencing in multi-voltage systems
-
Reducing standby power consumption in battery-powered applications
-
Remote shutdown capability for safety systems
-
Microcontroller-controlled power management
Enable Pin Operation:
-
EN = HIGH (1.4V – VIN): Module ON (normal operation)
-
EN = LOW (0V – 0.8V): Module OFF (shutdown mode)
-
Floating (disconnected): Module ON by default
Superior to LM2577 – The Key Differences:
| Feature | XL6009 (This Module) | LM2577 (Traditional) |
|---|---|---|
| Switch Current | 4A peak | 3A peak |
| Switching Frequency | 400kHz | ~52kHz |
| Maximum Efficiency | Up to 94% | 75-85% |
| Output Ripple | Lower (<50mV) | Higher (80-120mV) |
| Compensation | External (design flexibility) | Internal (simplified) |
The XL6009’s 400kHz switching frequency is a dramatic upgrade over the LM2577’s 52kHz. This higher frequency allows for the use of smaller, lower-cost filter capacitors while achieving lower output ripple and a more compact module design . The higher efficiency (up to 94%) means less power is wasted as heat, improving reliability in compact designs.
Wide Operating Range:
-
Input Voltage: 3V – 32V (Optimal 5V – 32V)
-
Output Voltage: 5V – 50V (adjustable via onboard potentiometer)
-
Maximum Output Current: 2.5A (derate based on input/output conditions)
-
Maximum Input Current: 4A
-
Operating Temperature: -40°C to +85°C
Key Applications:
-
Automotive Voltage Regulation: Stabilizes vehicle electrical systems where voltage can fluctuate
-
Battery-Powered Devices: Converts single-cell Li-Ion batteries (3.7V) to 5V, 9V, or 12V
-
LED Lighting: Drives 12V or 24V LED strips from 5V USB power banks
-
Industrial Equipment: Provides higher voltage rails for sensors and actuators
-
Remote Power Control: Enable pin allows microcontroller-based power management
Important Operating Note: This module is a step-up (boost) converter only. The output voltage must be set higher than the input voltage for proper regulation. If the input exceeds the set output, the module cannot step down, and the output will approximately follow the input, potentially damaging your load.
Whether you are an electronics hobbyist, an IoT developer, or an industrial engineer, the XL6009 Step-Up Converter Module with Enable Pin provides a powerful, efficient, and user-friendly solution for all your voltage boosting needs.
