The RTQ2072 is an integrated PMIC with three step down converters and one high PSRR low-dropout (LDO) regulator for automotive camera applications. The high-voltage step down converter is operated with input voltage range up to 18.5V for Power Over Coax (POC) connection. Two low-voltage step down converters provide constant output voltage. All step down converters operate in a forced fixed-frequency PWM mode. The LDO output voltage is easily set via an external resistor. The RTQ2072 provides 10 power sequences by a resistor for flexibility. The RTQ2072 is available in a WETD-VQFN-16L 3x3 package with dimple lead type wettable flanks.
