    Package

The TPS43330-Q1 and TPS43332-Q1 devices (TPS4333x-Q1) include two current-mode synchronous buck controllers and a voltage-mode boost controller. The TPS4333x-Q1 family of devices is ideally suited as a pre-regulator stage with low IQ requirements and for applications that must survive supply drops due to cranking events. The integrated boost controller allows the devices 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 can be enabled 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 can be programed over 150 kHz to 600 kHz or synchronized to an external clock in the same range. Additionally, the TPS43332-Q1 device offers frequency-hopping spread-spectrum operation.
