Key Differentiators
- Automotive AEC-Q100 qualification (vs TPS51200DRCR)
- Wide operating temperature range (vs TPS51200DRCR)
- Pin-to-pin compatibility with non-automotive variants (vs TPS51200DRCR)
Design Notes
Place input and output capacitors as close to the VIN and VTT pins as possible to minimize parasitic inductance. Use a 10 µF ceramic capacitor on the input and a 20 µF ceramic capacitor on the output. The exposed thermal pad should be connected to a large copper area for effective heat dissipation.
The TPS51200QDRCRQ1 can dissipate significant power when sourcing or sinking 2 A. Ensure adequate copper area on the PCB to keep the junction temperature within limits. The thermal pad must be soldered to a thermal relief pattern with multiple vias to the ground plane for optimal heat transfer.
Do not exceed the input voltage range of 6.5V. Ensure the VTTREF pin is properly connected to the VLDO output or an external reference. The enable pin should be driven by a logic signal for proper power sequencing. Avoid placing the output capacitor too far from the VTT pin, as this can cause instability.
