The TPS43333-Q1 includes two current-mode synchronous buck controllers and a voltage-mode boost controller. The device is ideal for use 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 device to operate down to 2 V at the input without seeing a drop on the buck-regulator output stages. At light loads, one can enable the buck controllers 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 programmable over 150 kHz to 600 kHz or can synchronize to an external clock in the same range.
