Key Differentiators
- Wider input voltage range (6V) vs TLV62090 (vs TLV62090RGTR)
- Automotive grade option available (vs TPS62090-Q1)
- Higher efficiency and lower quiescent current vs older TPS62085 (vs TPS62085)
Design Notes
For optimal performance, place the input capacitor (10 µF) and output capacitor (22 µF) as close as possible to the VIN and VOUT pins. Use a solid ground plane and minimize loop area for the switch node. The exposed thermal pad must be soldered to a large copper area for heat dissipation. Refer to the TPS62090 datasheet for recommended layout guidelines.
The TPS62090 uses DCS-Control™ topology, which requires a minimum output capacitance of 22 µF for stability. Use ceramic capacitors with low ESR. The input capacitor should be at least 10 µF. For high load transients, consider increasing output capacitance to improve transient response.
At 3A output, the power dissipation can be significant. For example, at VIN=5V, VOUT=1.8V, the efficiency is around 90%, resulting in about 0.6W dissipation. The VQFN package has a thermal resistance of approximately 40°C/W, so the junction temperature rise is about 24°C. Ensure adequate copper area on the PCB to keep the junction temperature below 125°C.
