CA-1253 DC-DC Step-Down Power Module 12V to 5V and 3.3V

The CA-1253 DC-DC Step-Down Power Supply Module is a highly efficient multi-output buck converter designed to step down a 12V DC input into stable 5V and 3.3V outputs, while also providing a 12V pass-through. This compact power board is widely used as a replacement and repair module for LCD monitors (such as BenQ and other major brands) where the internal power supply rails have failed. It provides a reliable, low-ripple power source to keep your display logic and panel running smoothly.

Perfect for makers, students, and hardware repair engineers, this module is also highly compatible with microcontrollers like Arduino, ESP32, and Raspberry Pi that require dual-voltage rails (5V and 3.3V) simultaneously. Equipped with high-quality filter capacitors and a robust buck regulator circuit, the CA-1253 ensures stable voltage regulation under varying loads, making it an indispensable tool for custom embedded systems and DIY electronics prototyping.

Features:

• Multi-Output Design: Provides simultaneous 12V, 5V, and 3.3V DC outputs from a single 12V input.
• LCD Repair Companion: Specifically designed for troubleshooting and repairing power boards in BenQ and other LCD monitors.
• Stable Voltage Regulation: Features high-quality electrolytic capacitors and an onboard inductor for low-ripple, stable output.
• Compact Form Factor: Easily fits into tight spaces inside monitor chassis or custom project enclosures.
• Convenient Connectivity: Equipped with standard multi-pin JST-style headers for secure and easy wiring.

Package Includes:

1 x CA-1253 DC-DC Step-Down Power Module 12V to 5V and 3.3V
