Product details
Overview
TPS6503200JRGERQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive power management IC designed for camera modules, integrating three step-down converters (BUCK1: 4.0–18.3 VIN, 2.5–4.0 VOUT, 800 mA; BUCK2/BUCK3: 2.5–5.5 VIN, 0.9–1.9 VOUT, 600 mA each) and one low-noise LDO (2.5–5.5 VIN, 1.8–3.3 VOUT, 300 mA), all operating in forced fixed-frequency PWM mode with spread-spectrum clocking for EMI reduction.
For engineers reviewing the TPS6503200JRGERQ1 datasheet, TPS6503200JRGERQ1 pinout, TPS6503200JRGERQ1 application, or TPS6503200JRGERQ1 equivalent, this PMIC delivers sequenced, low-noise, high-PSRR power for image sensors and serializers in PoC-based automotive vision systems - with validated thermal performance across –40°C to +125°C ambient.
Technical Context
The TPS6503200JRGERQ1 implements independent input rails for each regulator, enabling flexible power sequencing and fault isolation in multi-rail camera sensor subsystems. BUCK1 supports direct connection to Power-over-Coax (PoC) lines up to 18.3 V, while BUCK2/BUCK3 and the LDO accept lower-voltage intermediate rails (2.5–5.5 V), allowing cascaded or distributed supply architectures.
All regulators operate in forced PWM mode at 2.3 MHz (fixed frequency), eliminating audible noise and ensuring predictable EMI behavior; BUCK1 includes integrated spread-spectrum clocking to further suppress peak emissions without compromising regulation accuracy or transient response.

FAQ
What is the maximum input voltage supported by TPS6503200JRGERQ1?
The TPS6503200JRGERQ1 supports up to 18.3 V on its BUCK1 input (VIN1), enabling direct connection to Power-over-Coax (PoC) lines without external pre-regulation. BUCK2, BUCK3, and the LDO accept 2.5 V to 5.5 V inputs - making the device suitable for both primary PoC-fed and secondary intermediate-rail architectures. This dual-input capability simplifies system-level power design in automotive camera modules.
Does TPS6503200JRGERQ1 support power sequencing control?
Yes, the TPS6503200JRGERQ1 provides four independent enable inputs (EN1, EN2, EN3, ENLDO) and four corresponding open-drain power-good outputs (PGOOD1–PGOODLDO), enabling precise, user-defined power-up and power-down sequencing. This capability is critical for avoiding latch-up or initialization faults in multi-rail image sensor subsystems - especially when coordinating serializer, sensor core, and analog front-end power domains.
Is TPS6503200JRGERQ1 qualified for automotive use?
Yes, the TPS6503200JRGERQ1 is AEC-Q100 Grade 1 qualified, with full characterization and testing across –40°C to +125°C ambient temperature. It meets automotive reliability standards including HTOL, TC, UHAST, and ESD (HBM ±2 kV), and is manufactured in TI's IATF 16949-certified facilities - ensuring suitability for safety-critical camera applications in ADAS and automated driving systems.
What package type and thermal features does TPS6503200JRGERQ1 use?
The TPS6503200JRGERQ1 uses a 4.0 mm × 4.0 mm, 24-pin VQFN package (RGE) with wettable flanks and an exposed thermal pad (Pin 25). The thermal pad must be soldered to a PCB copper plane for effective heat dissipation and EMI suppression. Wettable flanks enable automated optical inspection (AOI) of solder joint quality - a key requirement for zero-defect automotive manufacturing processes.
How does TPS6503200JRGERQ1 reduce electromagnetic interference (EMI)?
The TPS6503200JRGERQ1 reduces EMI through two integrated techniques: (1) forced fixed-frequency PWM operation at 2.3 MHz - placing switching energy outside the AM radio band and avoiding variable-frequency artifacts; and (2) spread-spectrum clocking (SSC) on BUCK1 - dithering the switching frequency to lower peak radiated emissions. These features help meet stringent CISPR 25 Class 5 requirements common in automotive camera deployments.
