Automotive buck-boost controller for wide-input designs
Switching frequency is adjustable from 100kHz to 600kHz and supports external clock synchronization, giving the designer room to push the fundamental above the AM band or align with the system switching noise window. Control features include enable, frequency control, power-good flag, and soft-start — enough to sequence multiple rails in an ECU or ADAS sensor module without a separate supervisor IC.
28-HTSSOP package and thermal management
Housed in a 28-lead PowerTSSOP with an exposed pad (28-HTSSOP), the LM5175QPWPTQ1 relies on the pad for thermal dissipation.
Active lifecycle — no LTB pressure
The LM5175QPWPTQ1 carries an active lifecycle status from Texas Instruments. No last-time-buy notices or EOL windows are in effect, which means it remains qualified for new-design insertion and production ramp. The ROHS3 compliance covers current EU and global substance restrictions without exemption expiry concerns.
