产品介绍 说明
The TPS43330-Q1/TPS43332-Q1 includes two current mode synchronous buck controllers and a voltage mode boost controller. The part is ideally suited as pre-regulator stage with low Iq requirements and systems that need to survive supply drops due to cranking events. The integrated boost controller allows the device to operate down to 2V at the input without seeing a drop on the Buck regulator output stages. At light loads, the buck controllers can be enabled to operate automatically in Low Power Mode consuming just 30µA of quiescent current. The buck controllers have independent soft start capability and power good indicators. External MOSFET protection is provided by current fold back in the buck controllers and cycle-by-cycle current limitation in the boost controller. 特性
