ITEM NAME:DC Boost Buck Step Up Down Converter 4.5 ~ 30V 3A Adjustable Power Module ds 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. Whatever the ending's perfect or not, you can't disappear from my world DC Boost Buck Step Up Down Converter 4.5 ~ 30V 3A Adjustable Power Module.Output current: up to 3A. Conversion efficiency: boost 87~91%; step-down 86~90%. First, the boost can also be reduced! Short circuit protection: Yes, hardware level short circuit protection circuit.
