Features Excellent Performance: The adjustable boost module adopts the XL6009E1 chip with high -frequency switching technology as the core chip, excellent performance. High -performance Improvement Module: The XL6009E1 module is a high -performance improvement module with a 4A switch current. It is a very practical device accessories. High Efficiency: DC-DC adjustable boost module is a built-in 4A high-efficiency MOSFET switch tube, with high efficiency as high as 94 %. Voltage DC Converter: The 4A power module voltage voltage DC converter has an ultra -wide input voltage 3V to 32V, and the best working voltage range is 5 to 32V. Ultra -wide output voltage 5V ~ 40V. High -effect: The boost module is that the ultra -high switching frequency is 400, and the smaller capacity filter capacitance can achieve good results. The ripples are small and the volume is smaller. Specification: Weight: 13g/0.5oz Model: XTW6009 boost module Module Type: Non-isolated boost (BOOST) Rectification method : Non-synchronous rectification Input range: 3V~32V Output range: 5V~40V Input current: Crest 4A (recommended to work for 1.5A or less for a long time), no load 18mA (5V input, 8V output, no load less than 18mA. The higher the voltage, the larger the no-load current.). Conversion efficiency : <94% (the larger the pressure difference, the lower the efficiency) Switching frequency : 400 Output ripple: 50mV (the higher the voltage, the larger the current, the larger the ripple) Load regulation rate: ±0.5% Voltage regulation rate : ±0.5% Working temperature : -40°C~ +85°C Size (L*W*H): 43*21*14mm/1.7*0.8*0.6inch  IN+ input positive IN- input negative! OUT+ output positive OUT-output negative. Measurement results are for reference only. Package List: 1 x Step-up Voltage Converter  Package List
