Features:XL6009E1 is a high performance boost module with 4A switching current. Adopting XL6009E1 chip with high frequency switching technology as the core chip, superior performance.Ultra-wide input voltage 3V ~ 32V, the best operating voltage range of 5 ~ 32V. Ultra-wide output voltage 5V ~ 35V. Built-in 4A high efficiency MOSFET switch tube with high efficiency up to 94%. Ultra-high switching frequency is 400KHz, and small capacity filter capacitance can achieve good results. The ripple is smaller and the volume is smaller. Specification:Weight: 13g/0.5ozModel: XTW6009 boost moduleModule Type: Non-isolated boost (BOOST)Rectification method : Non-synchronous rectificationInput range: 3V~32VOutput range: 5V~35VInput 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 : 400KHzOutput 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 : -40C~ +85CSize (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.Input VoltageOutput VoltageOutput CurrentOutput Power5V12V0.8A9.6W7.4V12V1.5A18W12V15V2A30W12V16V2A32W12V18V1.6A28.8W12V19V1.5A28.5WPackage List:1 x Step-up Voltage Converter .
