Product details
Overview
TPS65032001RGERQ1 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 TPS65032001RGERQ1 datasheet, TPS65032001RGERQ1 pinout, TPS65032001RGERQ1 application, or TPS65032001RGERQ1 equivalent, key selection criteria include PoC-compatible 18.3 V input capability, independent input rails for sequencing flexibility, wettable-flank VQFN-24 packaging, and -40°C to +125°C ambient operation for automotive camera systems.
Technical Context
The TPS65032001RGERQ1 implements three independent synchronous buck regulators and one linear regulator with separate input pins-enabling flexible power rail sequencing and isolation across camera sensor, serializer, and MCU subsystems. BUCK1 supports Power over Coax (PoC) interfaces via its extended 18.3 V input range and fixed 2.3-MHz switching frequency.
All regulators operate in forced PWM mode without pulse-skipping, ensuring consistent EMI profile and predictable transient response. The integrated LDO delivers high PSRR and low noise critical for image sensor analog supply domains, while spread-spectrum modulation on BUCK1 reduces peak radiated emissions without compromising regulation accuracy.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive camera PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS65032002QRGERQ1 | Different BUCK2/BUCK3 output voltage configuration (1.0 V / 1.2 V factory-set); same package, pinout, and thermal specs. | Pre-configured for specific sensor core voltages; less flexible than TPS65032001RGERQ1's adjustable range. | Select when fixed 1.0 V/1.2 V outputs align with target sensor datasheet requirements and simplify design-in. |
| MAX20049ATG/V+T | Three buck + one LDO architecture, but lacks spread-spectrum clocking and PoC-optimized 18.3 V input; uses 5×5 mm TQFN. | Better suited for non-PoC applications with lower input voltage (<16 V) and less stringent EMI constraints. | Consider only if PoC interface is absent and board space allows larger footprint; verify LDO noise specs against sensor requirements. |
Compared with TPS65032001RGERQ1, the TPS65032002QRGERQ1 offers factory-trimmed outputs for faster qualification but reduced configurability, while the MAX20049ATG/V+T provides alternate sourcing with trade-offs in EMI control and PoC compatibility-neither is pin-compatible nor drop-in.

FAQ
What is the maximum input voltage supported by TPS65032001RGERQ1?
The TPS65032001RGERQ1 supports up to 18.3 V on its BUCK1 input (VIN1), enabling direct integration with Power-over-Coax (PoC) systems in automotive camera applications. This rating is absolute maximum and validated per AEC-Q100 stress testing protocols. Exceeding 18.3 V may cause permanent damage. Input filtering and transient protection must be implemented externally per TI's SLVSHJ1 layout guidelines.
Does TPS65032001RGERQ1 support hardware-based power sequencing?
Yes, the TPS65032001RGERQ1 provides independent enable (EN1–EN3, EN_LDO) and power-good (PGOOD1–PGOOD3, PGOOD_LDO) signals for each regulator, allowing full hardware-controlled sequencing without MCU firmware involvement. These signals can be daisy-chained or combined using simple logic to implement custom ramp-up/down order, essential for avoiding latch-up in camera sensor and serializer interfaces.
Is the thermal pad (Pin 25) of TPS65032001RGERQ1 required to be soldered?
Yes, the exposed thermal pad (Pin 25) of the TPS65032001RGERQ1 must be soldered to a PCB thermal plane per TI's SLUA271 guidelines. It serves as the primary thermal conduction path and mechanical anchor. Omitting this connection risks thermal shutdown under load and compromises long-term reliability in automotive environments. Land pattern must match RGE0024K outline with ≥77% solder paste coverage.
Can TPS65032001RGERQ1 be used in non-automotive applications?
While the TPS65032001RGERQ1 meets AEC-Q100 Grade 1 specifications and is optimized for automotive camera use, its electrical functionality is not restricted to automotive contexts. However, its qualification, test documentation, and supply chain controls are automotive-specific. For industrial or consumer use, consider cost, availability, and whether AEC-Q100 overhead is justified-TI does not guarantee non-automotive qualification validity.
What is the purpose of the SS pin on TPS65032001RGERQ1?
The SS (Spread-Spectrum) pin on the TPS65032001RGERQ1 configures spread-spectrum modulation depth on the BUCK1 converter to reduce peak radiated EMI. When pulled high or low per datasheet settings, it adjusts modulation bandwidth and amplitude-enabling optimization for specific EMC test limits without changing switching frequency. This feature is unique to BUCK1 and does not affect BUCK2, BUCK3, or the LDO.
