Product details

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.

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.

Frequently asked questions

Is LM5175QPWPTQ1 automotive qualified?

Yes. The LM5175QPWPTQ1 is listed under the Automotive, AEC-Q100 series, which means it has passed the AEC-Q100 stress test qualification for automotive-grade integrated circuits. The junction temperature range of -40°C to 150°C supports under-hood and high-ambient deployments.

What is the lifecycle status of LM5175QPWPTQ1?

The lifecycle status is Active. No end-of-life or last-time-buy windows are in effect. The part is ROHS3 compliant and remains supported for new designs and production.
