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.

⚫ FMEA Compliant Pin Placement and Protection

Mechanisms

⚫ Three Step-Down Converters (HVBuck1,

LVBuck2 and LVBuck3)

 Peak Current Mode PWM Operation

 Fixed Switching Frequency at 2.1MHz

 EMI Reduction with Spread Spectrum and

Phase Shift

 HVBuck1 Input Voltage from 4V to 18.5V,

Adjustable Output Voltage and Up to 2A Output

Current

 LVBuck2 Input Voltage from 2.7V to 5V, Fixed

Output Voltage and 1.5A Output Current

 LVBuck3 Input Voltage from 2.7V to 5V, Fixed

Output Voltage and 750mA Output Current

 Pins Related to LVBuck2/LVBuck3 Allowable

Floating if Channel Unused
