Description  
The OPTIREG™ PMIC TLF30681QVS01 is a multiple rail Power Management IC (PMIC) for automotive  
applications, optimized for the use in Advanced Driver Assistance Systems (ADAS). The device consists of a  
battery connected buck regulator (Buck1) providing 3.3 V to external loads and to two low voltage post-  
regulators. The first post-regulator (Buck2) provides an output voltage of 1.25 V (output voltage adjustment via  
SPI in the range of 0.9 V to 1.3 V). The second post-regulator (Boost1) provides an output voltage of 5.0 V and is  
intended to supply up to two CAN transceivers. The TLF30681QVS01 supports 16-bit SPI communication to a  
microcontroller. SPI commands can read status information from the device and control features of the power  
regulators, such as PWM synchronization. The device operates at a nominal switching frequency of 2.2 MHz. The  
switching frequency is selectable via SPI from 1.8 MHz to 2.5 MHz in steps of 100 kHz. The switching regulators  
can synchronize to an external clock signal. The TLF30681QVS01 can provide a synchronization signal for other  
DC/DC regulators in the system. The TLF30681QVS01 provides two voltage monitoring channels with
