Infineon Technologies TLF30682QVS01 OPTIREG™ Power Management IC
Infineon TLF30682QVS01 OPTIREG™ Power Management IC is a multi-output Power Management IC (PMIC) for automotive applications. The device consists of a battery-connected buck regulator (Buck1) providing 3.3V to external loads and two low-voltage post-regulators. The first post-regulator (Buck2) is a buck regulator providing an output voltage of 1.25V. The second post-regulator (Boost1) provides an output voltage of 5.0V and is intended to supply one or two CAN transceivers.The TLF30682QVS01 supports 16-bit SPI communication to a microcontroller. The SPI commands support reading status information from the device and controlling features such as PWM synchronization and power regulator control. The device operates at a nominal switching frequency of 2.2MHz. The switching frequency can be selected via SPI with an operating range from 1.8MHz to 2.5MHz in steps of 100kHz. The switching regulators can be synchronized to an external clock signal. The TLF30682 can provide a synchronization signal for other DC/DC regulators in the system.
The TLF30682QVS01 provides two voltage monitoring channels with monitoring inputs and enabled outputs. These channels can be used to control and monitor external voltage regulators, which can be either LDOs or DC/DC switching regulators.
