Key Differentiators
- Dual-channel output with current sensing (vs TPS7B7050QPWPRQ1)
- Wide input voltage range with load dump protection (vs TPS7B6333QPWPRQ1)
- Adjustable output voltage (vs TPS7B6333QPWPRQ1)
Design Notes
Ensure input and output capacitors are placed close to the pins. Use a 10uF ceramic capacitor on each input and output for stability. The current sense output should be connected to a low-impedance load, such as an ADC input, to avoid accuracy degradation.
The HTSSOP package has an exposed thermal pad that must be soldered to a copper area on the PCB. For high input-to-output voltage differentials, calculate power dissipation and ensure the PCB copper area is sufficient to keep junction temperature below 125Β°C. Refer to the thermal impedance data in the datasheet.
Route the sense lines away from noisy switching nodes. Use a ground plane under the device to reduce noise. The enable pins can be tied together for simultaneous startup or controlled independently for sequencing.
