상품 특징

• 【Reliable Power Supply】 The TPS63802 chip ensures voltage conversion for your devices, automatically adjusting between boost and buck modes to maintain optimal performance even as your battery discharges. Whether you're powering a , camera, or IoT device, this module delivers a steady 1.8V output across the entire discharge cycle. With its energy-saving dual-mode design, you can enjoy up to 90% efficiency under light loads, making it Suitable for long-lasting projects.
• 【Space-Saving Design】 Designed with compactness in mind, this USB power module measures just 17.4mm x 26.2mm, allowing you to fit it into tight spaces without compromising functionality. Its vertical welding capability further reduces footprint, Suitable for small electronics like smartwatches or portable speakers. Plus, the full ceramic capacitor design minimizes ripple noise to 5mVpp, ensuring clean power delivery every time.
• 【Versatile Output Options】 Customize your power needs with three jumper-selectable output voltages: 3.3V (1.3A), 4.2V (1A), or 5V (0.9A). Simply disconnect the jumpers and solder the appropriate resistor using our easy-to-follow formula. This flexibility makes it an excellent choice for a wide range of applications, from charging smartphones to powering development boards.
• 【Low Ripple, High Performance】 Our module boasts industry-leading ripple control, thanks to its full ceramic capacitor design. At just 5mVpp, it’s six times quieter than s, protecting sensitive components like ADC sensors from interference. Whether you’re building a precision tool or a consumer gadget, this low-noise performance ensures reliable operation every time.
• 【Efficient Energy Management】 Save energy and extend battery life with our dual-mode energy management system. In conventional mode, dynamic response takes priority, while power-saving mode boosts efficiency to over 90% during light loads. For even greater savings, short the PS pin or remove the LED to reduce idle power consumption from 50μA to just 1μA. It’s the ultimate solution for users who demand both performance and sustainability.
