Product details
Overview
TPS65035000RZDRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive power management IC designed for camera modules, integrating three step-down converters (BUCK1: 1.5 A, 4–18.3 VIN, 2.5–4.0 VOUT; BUCK2/BUCK3: 1.2 A each, 0.9–1.9 VOUT) and one adjustable LDO (300 mA, 1.8–3.3 VOUT, I²C-controlled), all operating in fixed 2.3-MHz PWM mode with spread-spectrum EMI reduction.
For engineers reviewing the TPS65035000RZDRQ1 datasheet, TPS65035000RZDRQ1 pinout, TPS65035000RZDRQ1 application, or TPS65035000RZDRQ1 equivalent, this device supports PoC-enabled camera systems requiring robust sequencing, low-noise biasing, and thermal reliability across –40°C to +125°C ambient operation.
Technical Context
The TPS65035000RZDRQ1 implements independent input rails for each regulator-BUCK1 accepts up to 18.3 V for direct Power over Coax (PoC) integration, while BUCK2, BUCK3, and the LDO share a 2.5–5.5 V domain-enabling flexible power sequencing and fault isolation in multi-rail camera sensor subsystems.
All regulators operate in forced fixed-frequency PWM mode at 2.3 MHz with integrated spread-spectrum clocking; the LDO features high PSRR and I²C-adjustable output voltage, supporting dynamic voltage scaling for image signal processors and serializer/deserializer ICs in surround-view and driver-monitor applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range (BUCK1) | 4.0 V to 18.3 V - enables direct connection to automotive PoC lines without external pre-regulation. |
| Output Current (BUCK1) | Up to 1500 mA - sufficient to power image sensors and analog front-ends in high-resolution camera modules. |
| Output Current (BUCK2/BUCK3) | Up to 1200 mA each - supports dual-core ISPs or high-speed SerDes logic rails with tight voltage tolerance. |
| LDO Output Range | 1.8 V to 3.3 V, I²C-adjustable - allows runtime optimization of sensor bias or MIPI PHY voltage without hardware change. |
| Switching Frequency | 2.3 MHz fixed PWM - avoids AM band interference and enables compact 1-µH inductor selection. |
| Ambient Temp Range | –40°C to +125°C - meets AEC-Q100 Grade 1 requirements for under-hood and exterior camera placement. |
| EMI Reduction | Integrated spread-spectrum clocking - lowers peak radiated emissions by >10 dB without external filtering. |
Pinout & Package
TPS65035000RZDRQ1 is housed in a 3.0 mm × 3.5 mm, 22-pin WQFN-FCRLF (RZD) package with wettable flanks and an exposed thermal pad requiring PCB soldering for thermal and mechanical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN1 | BUCK1 input supply | Accepts 4–18.3 V PoC rail; must be decoupled with ≥10 µF ceramic capacitor near pin. |
| VOUT1 | BUCK1 regulated output | Delivers 2.5–4.0 V at up to 1500 mA; connects directly to camera sensor core or analog supply. |
| VIN23 | Shared input for BUCK2/BUCK3 and LDO | 2.5–5.5 V domain powers digital logic rails and LDO input; requires separate bulk capacitance. |
| VOUT2 / VOUT3 | BUCK2 and BUCK3 outputs | Independent 0.9–1.9 V outputs for ISP cores or SerDes logic; each supports 1200 mA continuous load. |
| VOUT_LDO | LDO regulated output | I²C-programmable 1.8–3.3 V at ≤300 mA; used for low-noise MIPI PHY or sensor interface biasing. |
| SCL / SDA | I²C interface | Standard-mode (100 kHz) or fast-mode (400 kHz) control bus for dynamic voltage configuration and status readback. |
| EN_BUCK1 / EN_BUCK23 / EN_LDO | Individual enable inputs | Supports precise power-up/down sequencing via MCU GPIO or dedicated timing controller. |
| PGOOD1 / PGOOD23 / PGOOD_LDO | Power-good status outputs | Open-drain signals indicate regulation stability; used for system-level fault detection and reset coordination. |
| EPAD | Exposed thermal pad | Mandatory solder connection to internal PCB ground plane for thermal dissipation and mechanical anchoring. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive camera PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS65035100RZDRQ1 | Same package and pinout; differs only in factory-programmed BUCK1 output voltage (3.3 V fixed vs. adjustable 2.5–4.0 V). | Eliminates need for external feedback resistors but lacks runtime voltage flexibility via I²C. | Select when fixed 3.3 V sensor core supply suffices and firmware configurability is unnecessary. |
| MAX20049ATG/V+T | 3-channel buck + LDO, but no spread-spectrum; 2.2 MHz switching; smaller 16-pin 3×3 mm TQFN package. | Lacks PoC-rated 18.3 V input and independent VIN domains; limited to lower-power camera modules. | Consider for space-constrained interior cameras where PoC support and full AEC-Q100 Grade 1 thermal margin are not required. |
Compared with TPS65035000RZDRQ1, the TPS65035100RZDRQ1 offers identical layout compatibility but reduced firmware adaptability, while the MAX20049ATG/V+T trades PoC readiness and thermal headroom for footprint savings in non-coaxial applications.

FAQ
What is the maximum input voltage supported by TPS65035000RZDRQ1?
The TPS65035000RZDRQ1 supports up to 18.3 V on its BUCK1 input (VIN1), enabling direct connection to Power over Coax (PoC) infrastructure in automotive camera systems. This eliminates the need for external pre-regulators and simplifies front-end power architecture while maintaining AEC-Q100 Grade 1 reliability across –40°C to +125°C ambient conditions.
Does TPS65035000RZDRQ1 support I²C-based voltage programming?
Yes, the TPS65035000RZDRQ1 supports I²C-based programming of its LDO output voltage across a 1.8 V to 3.3 V range. The device uses standard-mode (100 kHz) or fast-mode (400 kHz) I²C communication on dedicated SCL/SDA pins, allowing dynamic adjustment during system operation-for example, to match sensor gain states or optimize MIPI PHY voltage in different imaging modes.
What package type and thermal requirements apply to TPS65035000RZDRQ1?
TPS65035000RZDRQ1 uses a 3.0 mm × 3.5 mm, 22-pin WQFN-FCRLF (RZD) package with wettable flanks and an exposed thermal pad. The EPAD must be soldered to a thermally robust PCB ground plane to ensure safe operation at full load across the –40°C to +125°C ambient range; TI recommends ≥6 thermal vias under the pad connected to inner-layer ground planes.
How does TPS65035000RZDRQ1 reduce electromagnetic interference?
The TPS65035000RZDRQ1 integrates spread-spectrum clocking across all switching regulators, dithering the 2.3-MHz fundamental frequency by ±1% to distribute switching energy and lower peak radiated emissions. This feature helps meet stringent CISPR 25 Class 5 limits for automotive camera modules without requiring additional EMI filters or shielded cables.
Is TPS65035000RZDRQ1 qualified for automotive safety-critical systems?
TPS65035000RZDRQ1 is AEC-Q100 Grade 1 qualified (–40°C to +125°C ambient), with full reliability testing including HTOL, temperature cycling, and ESD per ISO 10605. While it is not ASIL-certified as a standalone safety element, it is widely deployed in ASIL-B and ASIL-C camera systems as part of TI's functional safety-capable power architecture, with documentation supporting FMEDA and failure mode analysis.
