10 Pieces 3.3V Regulator Module Voltage Reducer DC to DC 12V 24V 5-28V to 3.3V 1.5A Buck Converter Power Supply Transformer Module

Features: Input: 5-28V Output: 3.3V Output current: 1.5A Conversion efficiency: 96% Operating Temperature: -40 ° C to +85 ° C Size: 17.5x12.3x4.3mm Output ripple: <30mV Switching frequency: 1-1.5 MHz (max) Output accuracy: ± 0.1V No-load current: <1mA Attentions: 1. Please pay attention to the positive and negative pole of the regulator module. You can mark the positive and negative pole on the back of the circuit board before you using this module. 2. When you use the module with an inductive load, please pay attention to protect the current in the rear stage. 3. When you use a steering gear or a motor, it may generate large ripple, which may affect the chips in the rear stage circuit. You can add the Zener and capacitor to protect it. 4. If you use high current for a long time, please do a good job of heat dissipation. Package Included: 10* 3.3V mini dc buck converter Module
