DESCRIPTION  
The TPS43335-Q1/TPS43336-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. The switching frequency can be programmed over 150 kHz to 600 kHz or synchronized to an  
external clock in the same range. Additionally, the TPS43336-Q1 offers frequency-hopping spread spectrum  
operation.
