TPS62810QWRWYRQ1 Overview
A synchronous buck converter is a type of switching voltage regulator that steps down a higher input voltage to a lower output voltage with high efficiency, typically above 90%. Within the power management IC hierarchy, buck converters sit alongside LDOs and boost converters and are preferred whenever load current or efficiency demands exceed what a linear regulator can dissipate. The TPS62810QWRWYRQ1 belongs to the TPS6281x-Q1 family of pin-to-pin 1A, 2A, 3A, and 4A automotive converters.
Key features include AEC-Q100 qualification (temperature grade 1, -40C to +125C ambient), Functional Safety-Capable documentation to support ISO 26262 system design, and peak current mode control topology for fast transient response. Low-resistive integrated switches minimize conduction losses, while the adjustable switching frequency can be synchronized to an external clock to control EMI. A power-good output, enable pin, and soft-start support robust power sequencing in multi-rail systems.
The device is designed for automotive applications such as infotainment and advanced driver assistance systems (ADAS). Reference designs pair the TPS62810-Q1 with an LM63635-Q1 bus converter switching at 2.1 MHz, with the load converters switching at 2.2 MHz to ease filtering. Typical rails include core supplies for processors, camera and radar modules, and communication modules in vehicles.
When designing with this converter, choose input and output capacitors and the inductor per the datasheet guidelines to maintain stability and minimize output ripple. Use thermal vias under the exposed pad to optimize heat dissipation at full 4A load.

Typical Applications
TPS62810QWRWYRQ1 is suitable for 6 applications: Automotive Infotainment, ADAS Camera Modules, Automotive Radar Sensor Power, Processor Core Rail Point-of-Load, Communication Modules (Telematics), Cluster and Display Power.
Automotive Infotainment
The TPS62810QWRWYRQ1 powers infotainment processor cores and I/O rails from 5V or pre-regulated automotive supplies, converting from 2.75V to 6V input down to 0.6V and above at up to 4A. Its peak current mode control gives fast transient response during graphics load bursts, and the external clock synchronization at 2.2 MHz keeps switching noise out of AM/FM and audio bands in the head unit. AEC-Q100 grade 1 qualification and the wettable-flank QFN package satisfy automotive assembly and reliability requirements.
Recommended
ADAS Camera Modules
Camera sensor and serializer rails in ADAS modules benefit from the TPS62810QWRWYRQ1's clean, adjustable 0.6V+ output and 4A capability for image processor cores. The synchronizable switching frequency allows designers to place the switching band away from sensitive analog and MIPI domains, and the power-good output supports sequencing of sensor power-up. Its 2x3mm footprint fits the tight board space typical of compact automotive camera clusters operating across -40C to +125C.
Recommended
Automotive Radar Sensor Power
Radar front-end SoCs require stable core and analog rails with low ripple; the TPS62810QWRWYRQ1's peak current mode topology and selectable switching frequency help keep noise out of the mmWave receive path when synchronized appropriately. With 4A capacity from a 2.75V-6V input, it supports both the digital baseband core and companion loads in a single compact stage, while AEC-Q100 grade 1 and functional-safety documentation ease system-level ISO 26262 design analysis.
Recommended
Processor Core Rail Point-of-Load
As a point-of-load converter, the TPS62810QWRWYRQ1 steps a 5V intermediate bus down to processor core voltages starting at 0.6V with up to 4A of current. Peak current mode control provides fast load-transient response for clock-gated cores, and the enable pin plus power-good output allow sequenced multi-rail power-up controlled by a supervisor or PMIC. Synchronous rectification delivers high efficiency, reducing heat in enclosed automotive electronics modules.
Recommended
Communication Modules (Telematics)
Telematics and connectivity modules combine high-current digital rails with RF-sensitive sections. The TPS62810QWRWYRQ1 supplies up to 4A for modem and application processor rails while its adjustable frequency supports coexistence planning with GNSS and cellular receivers. External synchronization lets several converters switch interleaved, reducing input ripple, and the compact 2x3mm wettable-flank package suits the dense layouts of automotive telematics boxes.
Recommended
Cluster and Display Power
Digital cluster and display modules draw dynamic load from backlights, display SoCs, and memory. The TPS62810QWRWYRQ1's fast peak current mode loop tracks these load steps with minimal undershoot, and its power-good flag enables supervision of the display rail sequence. Operating from a 5V rail with up to 4A output, it covers most display processor core needs, while AEC-Q100 grade 1 qualification supports the extended temperatures behind vehicle windshields.

Design Notes
At full 4A load with a 5V input and 3.3V output, conduction losses in the integrated switches dominate power dissipation. Connect the VQFN-9 exposed pad to a ground plane through an array of thermal vias under the device, and provide at least 1 square inch of copper on outer layers. Verify junction temperature stays within the -40C to +125C AEC-Q100 grade 1 window at worst-case automotive ambient.
Keep the input capacitor as close as possible to the PVIN/PGND pins and the inductor tight to the SW pin to minimize the high-frequency switching loop area. Route the VOS feedback sense line away from the SW node to prevent noise coupling into the regulation loop. Follow the PCB layout section of the TI TPS6281x-Q1 datasheet (Rev. K) for the recommended 2x3mm footprint and via placement.
Use the SS/SYNC pin to synchronize the TPS62810-Q1 to 2.2 MHz when it follows an LM63635-Q1 bus converter running at 2.1 MHz, as in the TI reference design. Spacing the switching frequencies apart and synchronizing to a common clock prevents beat-frequency artifacts and simplifies input filtering for conducted emissions compliance in automotive EMC testing.
Do not exceed the 6V maximum input rating - clamp or pre-regulate load-dump-adjacent supplies upstream. Select the inductor value and saturation current per the datasheet design procedure; an undersized inductor saturating at 4A peak current causes erratic regulation. The enable pin must not float in automotive applications - tie it through a divider or drive it from a sequencing controller for deterministic startup.
