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/0.5oz Model: XTW6009 boost module Module Type: Non-isolated boost (BOOST) Rectification method : Non-synchronous rectification Input range: 3V~32V Output range: 5V~35V 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 : 400KHz 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.
