The RTQ2072A-QT/RTQ2072B-QT is a highly integrated PMIC designed for automotive camera applications. It includes three buck converters and one high PSRR low-dropout (LDO) regulator. The high-voltage buck converter operates with an input voltage range of up to 18.5V, suitable for Power Over Coax (POC) connections. Two low-voltage buck converters provide a constant output voltage. All buck converters operate in a forced fixed-frequency PWM mode. The LDO output voltage can be easily set via an external resistor. The RTQ2072A-QT/RTQ2072B-QT supports 10 power sequences, configurable through a resistor. The ICQ is available in a WETD-VQFN-16L 3x3 package with dimple lead type wettable flanks.The recommended junction temperature range is -40°C to 150°C and the recommended ambient temperature range is -40°C to 125°C.
