The TPS62067QDSGRQ1 is a highly efficient, synchronous step-down converter from Texas Instruments that delivers up to 2 A of output current with an input voltage range of 2.9 V to 6 V, making it an excellent automotive power solution for converting from a 5-V or 3.3-V system supply rail. This automotive 3-MHz 2-A DC-DC converter operates at a fixed switching frequency, automatically enters power-save mode at light loads to sustain efficiency across the entire load range, and provides an open-drain power-good output. Packaged in a compact 8-WSON housing, this AEC-Q100 qualified power IC is optimized for use with only a tiny 1-µH inductor and a 10-µF output capacitor to achieve the smallest solution size, and it is functional-safety-capable to support modern automotive system design.
Application Scenarios
● Automotive infotainment and instrument clusters: powering navigation systems, digital cluster displays, and head-unit rails that demand low-ripple 5-V/3.3-V conversion.
● ADAS platforms: supplying efficient point-of-load rails for sensor modules, camera systems, and radar signal chains.
● Telematics and body electronics: ideal for ECUs, CAN transceivers, and always-on processor rails in this TI power management IC family.
● General automotive and industrial designs: well suited for battery-powered DSPs, processors, FPGA core voltages, and space-constrained portable devices requiring a synchronous step-down converter.
FAQ
Q: What is the main advantage of the TPS62067QDSGRQ1 over the TPS62067A-Q1? A: The TPS62067-Q1 combines a power-save mode for light-load efficiency with a power-good output, whereas the TPS62067A-Q1 runs in fixed-frequency PWM mode for noise-sensitive designs.
Q: What external components are recommended? A: A 1-µH inductor with a 10-µF output capacitor delivers the smallest footprint and best regulation performance.
Alternative automotive buck converter Models
1. TPS628502-Q1: TI's recommended newer version, a 2.7-V to 6-V, 2-A automotive step-down converter in a smaller 2.1 × 1.6-mm SOT583 package with reduced BOM cost, higher efficiency, and ±1% output accuracy.
2. TPS62812-Q1: A 2.75-V to 6-V, 2-A automotive buck converter in a 2 × 3-mm wettable-flank QFN package featuring adjustable frequency and spread-spectrum control.
3. TPS62067AQDSGRQ1: The same-footprint fixed-frequency PWM variant, ideal for applications requiring continuous PWM operation with lower noise.
