DC-DC Power Supply Module ±5V 600mA Ultra-Low Ripple 6.5–30V
DC-DC Power Supply Module — Single to ±5V Dual Output, Ultra-Low Ripple
Convert a wide-range DC input (6.5V–30V) into a clean, stable dual ±5V output with this compact switching power supply module. Engineered for precision electronics projects, lab benches, audio circuits, and embedded systems, this module delivers ultra-low ripple and outstanding load regulation in a 6.25 cm × 4.5 cm footprint. Made in Mainland China.
Key Features
- Wide Input Range: Accepts DC input from +6.5V to +30V — compatible with a broad range of power sources and adapters.
- Dual ±5V Output: Each output rail (+5V and −5V) supports up to 600mA maximum (500mA recommended continuous).
-
Ultra-Low Output Ripple:
- +5V rail: <2.5mVpp (no-load, 6.5V–15V input); <6mVpp (up to 30V input); 2.5–7.5mVpp at 600mA load.
- −5V rail: <4.5mVpp (no-load, 6.5V–15V input); <9mVpp (up to 30V input); 4–9.5mVpp at 600mA load.
- Excellent Load Regulation: With 9V–24V DC input, load regulation is below 0.65% — output voltage stays rock-steady across varying loads.
- High Efficiency: +5V output efficiency exceeds 80%; −5V output exceeds 66% across a 9V–24V input range.
- Multiple Input Interfaces: Includes a DC power jack, screw terminal block, and pin header — ready for prototyping boards, enclosures, and custom wiring.
- Built-In Short-Circuit & Current-Limiting Protection: Safeguards both the module and your connected circuit against accidental shorts and overloads.
- Switching Power Supply Technology: DC-DC conversion via dedicated switching power supply chip ensures consistent performance and thermal efficiency.

Frequently Asked Questions
Q: What input voltage range does this DC-DC power supply module support?
A: This module accepts a wide DC input voltage range of +6.5V to +30V, making it compatible with many standard power supplies, bench supplies, and battery packs commonly used in electronics projects.
Q: Can I use both ±5V output rails simultaneously at full load?
A: Yes. Each output rail (+5V and −5V) independently supports up to 600mA. However, for sustained or continuous operation, a maximum of 500mA per rail is recommended to ensure long-term reliability and optimal thermal performance.
Q: What protection features does this module include?
A: The module features built-in short-circuit protection and current-limiting protection. These automatically engage to protect the module and your connected circuitry in the event of an accidental short or an overload condition, preventing damage to downstream components.
Q: How do I connect power to this module?
A: The module provides three convenient input interface options: a standard DC power jack, a screw terminal block, and a pin header. You can choose the interface that best suits your project enclosure, breadboard, or custom wiring setup.
