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.
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.
To help support system safety, the device includes voltage monitoring on all supply rails and a window-watchdog to monitor the MCU and DSP. Other features include a high-side driver which drives a warning-lamp LED, a reference voltage which is used as ADC reference in the MCU, DSP, and a shutdown comparator which, in combination with external NTC-resistor, switches off the device at too-low ambient temperature.
