CXCH76009电流模式升压DC转换器内置握手接口电路连接兼容QC2.0的手机和其他类似设备自动输出选择在5V和9V之间内置D-/D+接口带QC2.0A级设备

CXCH76009是一款电流模式升压DC-DC转换器，内置握手接口电路，可连接兼容QC2.0的手机和其他类似设备。如果接口成功，CXCH76009将自动将电压提高到9V和1.5A，以提供快速充电。如果插入的设备不兼容QC2.0，CXCH76009将提供高达5V/2.4A的快速充电。CXCH76009集成了一个超高效的MOSFET和Rds（ON）~40mΩ。这使得功率转换非常有效。内部补偿网络被罚款，以提供5V和9V操作的最佳补偿。这使得CXCH76009只能使用8个组件来提供12V/1A、9V/1.5A或5V/2A操作。软启动功能也在船上

The CXCH76009 is a current mode boost DC-DC converter with built-in handshake interface circuitry to QC2.0 compatible cellphones and other similar devices. If the interface is successful, CXCH76009 will automatically increase the voltage to 9V and 1.5A to provide fast charging. If the plugged device is not QC2.0 compatible, CXCH76009 will provide up to 5V/2.4A for fast charging. CXCH76009 integrates an super efficient MOSFET with Rds(ON) ~ 40mΩ. This makes power conversions very efficient. The internal compensation network are fined turned to provide the best compensation for both 5V and 9V operations. This allows CXCH76009to use only 8 components to provide either12V/1A； 9V/1.5A or 5V/2A operations. The soft-start function is also onboard.. The CXCH76009is available in the SOP8 package and provides space-saving PCB for the application fields.
