Typical Applications
TPS62130QRGTRQ1 is suitable for 6 applications: Automotive Infotainment Power, ADAS Sensor Module Supply, Industrial 24V Bus Point-of-Load, Battery-Powered Portable Instruments, Communications and Networking Equipment, Motor Drive and Servo Control Boards.
Automotive Infotainment Power
Automotive head units and displays run from 12V battery rails that see cold-crank dips and load-dump surges. The TPS62130QRGTRQ1's 3V to 17V input range and AEC-Q100 -40C to +125C qualification directly address this environment, converting 12V down to 3.3V or 5V at up to 3A for SoC, memory, and display supplies. Its adaptive DCS-Control switching up to roughly 2.5 MHz keeps harmonics out of AM-band-sensitive infotainment receivers, and the power-good output enables clean sequencing of the multi-rail processor tree.
Recommended
ADAS Sensor Module Supply
Radar, camera, and lidar modules in ADAS platforms need compact, efficient point-of-load conversion from 12V to core rails around 1.2V to 3.3V. The TPS62130QRGTRQ1 delivers 3A in a 3x3 mm VQFN footprint suited to space-constrained sensor boards, and its Q1 qualification meets automotive safety requirements. Placed after an upstream pre-regulator or TVS clamp, it provides tight regulation with fast DCS-Control transient response for bursty image-sensor and radar-SoC loads, while the enable and SS/TR pins support orderly power sequencing during module startup.
Recommended
Industrial 24V Bus Point-of-Load
Industrial controls, PLC I/O, and factory automation modules commonly use 12V or 24V intermediate buses. The 17V maximum input covers 12V rails directly and supports regulated intermediate buses, delivering up to 3A for processors, interface transceivers, and I/O drivers. DCS-Control provides quick load-transient response for motor-control microcontrollers, and the synchronous rectification eliminates an external Schottky diode, cutting BOM cost. The exposed-pad VQFN-16 dissipates heat efficiently on 2-oz copper boards typical of industrial designs.
Recommended
Battery-Powered Portable Instruments
Portable test equipment and battery-powered instruments benefit from the TPS62130QRGTRQ1's high efficiency synchronous buck and 100% duty-cycle mode, which allow the output to follow the input downward as the battery discharges, maximizing usable battery capacity. The 3V low-end input supports 3-cell alkaline or single-cell Li-ion stacks with headroom. Adjustable soft-start via SS/TR limits inrush at power-up, and the power-good flag can gate the load MCU until the rail is stable, improving system reliability in the field.
Recommended
Communications and Networking Equipment
Routers, switches, and optical modules use 12V backplane or adapter inputs and need efficient, low-noise point-of-load conversion for PHYs, MACs, and FPGAs. The TPS62130QRGTRQ1's roughly 2.5 MHz switching keeps switching artifacts above sensitive baseband bands, and the DCS-Control topology provides low output ripple that simplifies filtering for analog sections. At up to 3A it can power a mid-range FPGA core rail directly, and its small 3x3 mm footprint fits dense line-card layouts with limited board area.
Recommended
Motor Drive and Servo Control Boards
Brushed and BLDC servo controllers derive logic and gate-driver rails from 12V or 24V supplies. The TPS62130QRGTRQ1 supplies up to 3A for MCUs, gate-driver bias, and encoder electronics with fast transient response that tolerates the pulsed load profile of PWM stages. Its -40C to +125C range suits motor-adjacent thermal environments, and 100% duty-cycle mode maintains regulation during battery supply dips. The enable pin allows the controller MCU to disable the logic rail for fault handling or low-power standby.

Key Differentiators
- Full 3A capability in 3x3 mm VQFN-16 (vs TPS62140RGTR)
- AEC-Q100 automotive qualification (vs TPS62130RGTR)
- DCS-Control topology with 100% duty-cycle mode (vs TPS62150A-Q1)
Design Notes
Place low-ESR ceramic input capacitors (per datasheet recommendation, typically 10uF plus 0.1uF) directly across PVIN/PGND with minimal loop area. Connect the exposed thermal pad to a solid ground plane using an array of vias. Keep the SW node copper short and narrow to reduce radiated EMI. Follow the PCB layout section of TI datasheet TPS6213xA-Q1 (Rev. E) and TI EVM user guide layouts as the reference implementation.
At 12V input to 3.3V/3A output, efficiency of roughly 90-95% implies 0.5-1W of dissipation. The theta_JA of the VQFN-16 with exposed pad depends heavily on board copper; use at least 2x2 cm of ground-plane copper or thermal vias to keep junction temperature within the -40C to +125C automotive range under worst-case ambient. Run TI's thermal design tools or Webench for your exact operating point.
Do not exceed 17V input - automotive load-dump transients can far exceed this, so add upstream transient suppression (TVS or pre-regulator) on direct battery-fed designs. Use the SS/TR pin for soft-start to limit inrush; omitting it allows fast startup current peaks that may trip upstream current limits. Ensure the bootstrap capacitor between BST and SW is a 0.1uF ceramic placed close to the pins.
