Product: Boost converter module (input 9V–24V) What this product does Steps up (boosts) DC input voltages in the 9V to 24V range to higher voltages required by downstream electronics. Provides stable, lowripple output suitable for sensitive circuits and regulated power supplies. Key benefits — why you need it Reliable voltage boost for battery and vehiclebased systems: supports projects and equipment that require higher voltages than available from the source. Simple voltage checking: a touch button and indicator light display the measured voltage for quick, onboard verification. Flexible installation: screw terminals on both input and output make wiring fast and toolfriendly; a solder pad is available for permanent or compact assemblies. performance and stable operation: up to 4A maximum output current (recommended working current 2A), 92% efficiency, only 30mV output ripple, and a 400kHz switching frequency to minimize noise and maintain steady output. Wide operating temperature range (40°C to +85°C) for use in demanding environments. Compatibility and application Input voltage: 9V to 24V DC. Output current capability: max 4A (design for results at or below 2A continuous). Connection options: screw terminals for easy wiring; solder pad for permanent connections. Monitoring: touch button switch plus indicator light shows measured voltage. Practical use scenarios Automotive accessory power: boost a 12V vehicle battery to supply 24V sensors, actuators, or communication modules while driving. Prototyping and bench supplies: integrate into DIY adjustable regulated power supplies to obtain higher test voltages from common 12V adapters or battery packs. Industrial field equipment: provide stable boosted voltage for control modules or instrumentation in systems operating between 9V and 24V, including installations exposed to extreme temperatures. Performance and reliability details Maximum output current: 4A (for intermittent or peak loads). Recommended continuous working current: 2A (for reliable, longterm operation). Efficiency: up to 92% for reduced heat and longer battery runtime. Output ripple: approximately 30mV, suitable for many noisesensitive applications. Switching frequency: 400kHz. Operating temperature: 40°C to +85°C. Installation notes Use the screw terminals for fast, removable connections; use the solder pad for a secure, permanent connection when needed. Observe the recommended working current (2A) for continuous operation to ensure longterm stability and thermal reliability. This boost converter is suited to battery systems, power systems, DIY adjustable regulated power supplies, and various industrial equipment operating with 9V to 24V inputs, delivering efficient, lownoise boosted voltages and convenient onboard voltage indication.
