Amid the trend of multifunctional integration in portable devices, battery life has become a critical challenge for wearable devices and portable imaging systems. Awinic Electronics has launched the ultra-low-power Buck-Boost AWP3770X series chip, which precisely addresses PPG and VCM power supply challenges by optimizing quiescent power consumption, conversion efficiency, and dynamic adaptability. The series supports an input voltage range of 2.2V to 5.5V and an output voltage range of 2.025V to 5.2V, with a quiescent current of only 2.8μA, a shutdown current of 0.3μA, and a conversion efficiency of up to 95%. It also features fast dynamic response and seamless mode switching capabilities, making it suitable for low-power applications such as wearable devices, smartphones, and wireless earbud charging cases.
