OmniVision releases a new generation of ultra-low quiescent current high-efficiency synchronous buck converters WD1020/WD1021

     The explosive growth of IoT applications and wearable devices is inseparable from the empowerment of power management technology. Small and portable battery-powered devices, such as Bluetooth headsets, smart watches, video doorbells, item trackers, etc., are often compact in size, have limited battery capacity, and are required to be able to stand by for a long time and respond quickly. The low power consumption performance of the system and the device itself puts forward high requirements. Battery life and "wake up" response time are related to the core performance of the device. Therefore, synchronous buck converters with ultra-low quiescent current and ultra-fast transient response are favored by designers.

     OmniVision released a new generation of high-efficiency synchronous buck converters WD1020/WD1021. This series has an ultra-low 360nA quiescent current. High efficiency is still available at light loads as low as 10uA. Efficiency up to 97% over the full load range. Through the advanced peak current control architecture, the WD1020/WD1021 still has excellent dynamic response capability in a wide load range, which can effectively extend the battery life of battery-powered products, and is ideal for powering sensors, MCUs, wireless communications and other system components
