TPS65034003RZDRQ1

TPS65034003RZDRQ1 is a Texas Instruments automotive camera PMIC in a 22-pin WQFN package, the 03 NVM configuration of the TPS650340-Q1 for image-sensor modules from OmniVision, Sony, Samsung, SmartSens and onsemi. Three step-down converters plus one high-PSRR LDO deliver four rails: BUCK1 accepts 4.0 to 18.3 V from Power-over-Coax feeds and delivers up to 800 mA at 2.5 to 4.0 V, BUCK2 and BUCK3 convert 2.5 to 5.5 V into 0.9 to 1.9 V at up to 600 mA each, and the LDO supplies up to 300 mA at 1.8 to 3.3 V. All converters run forced fixed-frequency PWM at 2.3 MHz with spread-spectrum clocking to keep EMI low, and separate rail inputs maximize sequencing flexibility. The part is AEC-Q100 Grade 1 qualified over -40°C to +125°C in a 3.0 x 3.5 mm wettable-flank package. Selection advice: the 03 digits are the NVM variant code - rail voltages and sequencing are factory-set, so a different TPS650340 variant is not a drop-in substitute; verify the 03 rail map against your sensor before committing the design. Parameters verified against Texas Instruments documentation.
