The 1–5 V to 5 V DC-DC Boost Converter 1 A USB Output Module is a step-up voltage regulation device designed to convert a low DC input voltage into a stable 5 V DC output with USB interface support. It operates with an input range of 1–5 V DC and provides a regulated output of approximately 5.1–5.2 V DC, suitable for powering USB-compatible loads. The module supports a rated output current of up to 1 A–1.5 A depending on the input source, and operates at a switching frequency of 500 kHz for efficient power conversion. Its compact design allows integration into portable electronic systems and low-voltage battery-powered applications. It is compatible with single-cell lithium battery systems and low-power embedded devices.
