Description Perfect voltage regulator for mini quadcopter.such as QAV250 ZMR250 etc. Super light weight, 2 gram only. Very low noise which makes it perfect for FPV voltage regulation. Voltage adjustable, so you can dial it in to give you what you need 12v or 5v or anything else. Support 2s-6s RC flight batteries input. Please note: It is a buck module, can`t boost the voltage. For safety, It must be adjusted to desired voltage and check by multimeter before use. Module Properties: non-isolated buck Rectification: synchronous rectification Input voltage: 4.75V-23V Output voltage: 1.0V-17V Output Current: lowering the value of 3A, long 1.8A Conversion efficiency: 96% (maximum) Switching Frequency: 340KHz Output ripple: 30mV (no-load) Load regulation: 0.5% Voltage regulation: 2.5% Working temperature: -40 Centigrade to +85 Centigrade External dimensions: 17 * 11 * 3.8 (L * W * H) (mm) Features: Use integrally molded power inductor and synchronous rectifier control chip, smaller and more efficient. Package Choose 40 pcs Mini-360 DC-DC HM Buck Converter Step Down Power Supply Module
