Key Differentiators
- Automotive AEC-Q100 qualification (vs TPS62150A)
- Higher switching frequency (2.5 MHz) (vs TPS62160-Q1)
- Lower quiescent current (17 Β΅A) (vs TPS62152-Q1)
Design Notes
Place the input capacitor (10 Β΅F) and output capacitor (22 Β΅F) as close to the VIN and VOUT pins as possible to minimize parasitic inductance. Use a solid ground plane under the device and connect the exposed pad to the ground plane with multiple vias for optimal thermal performance. The SW node should be kept short and wide to reduce EMI.
The TPS62150A-Q1 in a 3x3 QFN package can dissipate up to 2W at maximum load. Ensure adequate copper area on the PCB (at least 1 square inch) connected to the exposed pad to keep the junction temperature below 125Β°C. For high ambient temperatures, consider using a thermal via array under the device.
Do not exceed the absolute maximum input voltage of 17V. Ensure the feedback resistor divider uses 1% tolerance resistors to maintain output voltage accuracy. The SS/TR pin can be used for tracking or soft-start; if unused, connect it to VIN through a resistor. Avoid using low-ESR ceramic capacitors without proper ESR compensation, as this can cause instability.
