Texas Instruments TPS43336QDAPRQ1

The TPS43335-Q1 and TPS43336-Q1 include two current-mode synchronous buck controllers and a voltage-mode boost controller. The devices are 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, 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. One can program the switching frequency over 150 kHz to 600 kHz or synchronize it to an external clock in the same range. Additionally, the TPS43336-Q1 offers frequency-hopping spread-spectrum operation.
