Description
General part information
TPS43330A-Q1 Series
The TPS43330A-Q1 device includes two current-mode synchronous-buck controllers and a voltage-mode boost controller. The device is ideally suited as a pre-regulator stage with low IQrequirements and for applications that must survive supply drops due to cranking events. The integrated boost controller allows the device to operate down to 2 V at the input without seeing a drop on the buck regulator output stages. At light loads, the buck controllers enable to operate automatically in low-power mode, consuming just 30 µA of quiescent current.
The buck controllers have independent soft-start capability and power-good indicators. Current foldback in the buck controllers and cycle-by-cycle current limitation in the boost controller provide external MOSFET protection. The switching frequency is programable over 150 to 600 kHz or is synchronized to an external clock in the same range.
