ITEM NAME:DC Boost Buck Step Up Down Converter 4.5 ~ 30V 3A Adjustable Power Module Descriptio n Description: Input voltage: 4.5 ~ 30V Output voltage: 0.5 ~ 30V Output current: up to 3A Output power: maximum 30W under natural heat dissipation, maximum 60W under wind cooling Output ripple: full load output voltage ripple is 30MV Conversion efficiency: boost 87~91%; step-down 86~90% Short circuit protection: Yes, hardware level short circuit protection circuit Working frequency: 180KHZ First, the boost can also be reduced! Example 1: The input voltage can be stable at 12 volts regardless of whether the input voltage is higher than 12 volts or lower than 12 volts! Example 2: Power the module 12 volts, the output can be stepped down to 5 volts, and can be boosted to 24 volts! Second, the XL6009 module is more efficient, more powerful, and the output voltage is more pure! Third, ultra-low output voltage ripple, 12 volts 3A output voltage ripple is only 20 millivolts, especially suitable for audio / power amplifier board, analog circuit power supply! Fourth, with a mobile phone charger or battery power, you can achieve adjustable DC power supply of 0.5 to 30 volts, very convenient! Specifications: Material: PCB Color: Picture Color Size: 54*29*21mm Package Included: 1* Automatic Buck-boost Power Module Note: Please be reminded that due to lighting effects and monitor's brightness/contrast settings etc, the color tone of the website's photo and the actual item could be slightly different.
