OmniVision released the compact 5V/2A step-down converter WD10721 Howell Group launched the 5V/2A step-down converter WD10721. This product has the characteristics of high efficiency, small size, light load mode support, etc. It is suitable for mobile phones, the Internet of Things, solid state drives and other compact intelligent devices.
In addition to providing CMOS image sensor, touch and display integrated driver (TDDI) solutions for mobile phones, computers, automobiles and other applications, OmniVision Group's power management chips are also equipped with many smart terminal devices. The recently launched 5V/2A DC-DC buck converter WD10721 is very suitable for smart devices with limited space such as mobile phones and IoT modules, but high efficiency requirements for power supply.
WD10721 is an optimized synchronous buck DC-DC converter. In COT mode, up to 2A output current can be provided at 2.1MHz typical switching frequency. In the shutdown state, the current consumption is less than 2 μ A。 By optimizing the upper and lower switches and drive circuits, the peak efficiency of WD10721 exceeds 95%. It supports the light load PFM power saving mode and 100% duty cycle to maintain high efficiency under various load conditions. WD10721 internal soft start circuit can limit the surge current during startup. The device also has perfect protection functions such as over-current protection and thermal shutdown.
