RTQ2072-QT
Automotive CIS/CCM PMIC for Ultra Compact Camera and
High Image Quality System
General Description
Features
⚫ AEC-Q100 Grade 1
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.
