The quick charging reference design from Renesas is able to delivering a excessive charging present of 10A. The reference design is as much as 98% environment friendly when the charging present is about at 2Amps. The reference design employs a high-efficiency present doubler with built-in Analog to Digital converters (ADC) for system monitoring. The microcontroller used within the reference design works as a USB transceiver and enhances the discrete digital IO management (Basic Objective Enter Output (GPIO) and devoted capabilities).
The reference design from Renesas can be utilized as a stand-alone 1S charger or might be applied into Laptops, smartphones, tablets, and so forth.
