Mini Step Down Power Supply Module Adjustable Voltage Converter for Wireless Device Charging Circuits

Description: Mini Voltage Converter Module, Input: 4.5-20V, Versatile Output: 1-16V Adj. or Fixed 1.8/2.5/3.3/5/9/12V, 2A Output, High Efficiency Main Features: 1. Supports input of 4.5-20V for wide usage in different power environments. 2. Multiple voltage outputs—adjustable or predefined—cater to varied electronics needs. 3. Delivers up to 97% efficiency, conserving energy and producing minimal heat. 4. Enables 2A continuous current with synchronous rectification for dependable load. 5. Space-efficient and high-integration design for modern small electronics. Specifications: Module Category: Synchronous , non-isolated Input Range: 4.5-20V Output: Adjustable (1-16V) and multiple fixed options (1.8/2.5/3.3/5/9/12V), selected on module Notice: Output always needs to be lower than input, not for voltage boosting. Max Current: 2A (short peaks 3A), 10W power handling Conversion Efficiency: ≤97% (commonly over 90% for 12V->5V/2A conversion) Switching Frequency: 800 KHz Output Ripple: ~20mV typical Working Temp: -40°C to +85°C. Higher temp lowers max output Safety: No overvoltage; short-circuit protection available but avoid long-term shorts Reverse Input: Not protected by default, diode required for safety Enable Input: Yes. HIGH (2-5V) = ON, LOW = OFF, default internal pull-up Mount: Solder connection I/O Method: Solder or pin compatible Pad Spacing: 2.54mm Physical Size: 19.5 x 14 x 4.7mm Materials: Plastic and metal Packing: 1 x Mini Step Down Module Reminders: 1. Color variations possible due to different display/light, refer to physical item. 2. Slight manual measurement differences may occur. The merchant warrants that their products comply with all applicable laws, and are offered only if they comply with Joom's policies and EU Product Safety and Compliance laws.
