3 Description  
The TPS65311-Q1 device is a power-management IC  
(PMIC), meeting the requirements of digital-signal-  
processor (DSP) controlled-automotive systems (for  
example, advanced driver-assistance systems). With  
the integration of commonly used supply rails and  
features, the TPS65311-Q1 device significantly  
reduces board space and system costs.  
Device HBM ESD Classification Level H1B  
Device CDM ESD Classification Level C4B  
Input Voltage Range: 4 V to 40 V, Transients up  
to 60 V; 80 V When Using External PMOS-FET  
Single-Output Synchronous-Buck Controller  
Peak Gate-Drive Current 0.6 A  
The device is capable of providing stable output  
voltages to the application, including a typical 5-V  
CAN-supply, from a varying input power supply (such  
as an automotive car battery) from 4 V to 40 V. The  
device includes one synchronous buck controller as a  
pre-regulator that offers flexible output power to the  
application. For post-regulation, the device includes  
two synchronous buck and one asynchronous boost  
converter, working at a switching frequency of 2.45  
MHz to allow for a smaller inductor which requires  
less board space. The two buck converters also offer  
internal loop compensation which eliminates the need  
for external compensation components. Furthermore,  
the device includes a low-noise linear regulator.
