Key Features
- AEC-Q100 Grade 1 automotive qualification ensures reliable operation from -40°C to 125°C in harsh vehicle environments
- 3A continuous output current with PFM/PWM mode switching optimizes efficiency from light to heavy loads on 2.7V to 6V rails
- Compact 8-pin SOT-5x3 (SOT583) package reduces PCB footprint to under 5 mm² for space-constrained automotive modules
Applications
The TPS628503QDRLRQ1 is designed for automotive infotainment, ADAS sensor modules, and body control units requiring a compact, efficient step-down regulator on 3.3V or 5V bus rails. Its AEC-Q100 Grade 1 rating and -40°C to 125°C operating range make it appropriate for under-hood and passenger compartment applications. The PFM mode enables low quiescent current in standby-heavy automotive systems such as keyless entry or always-on telematics.

Frequently Asked Questions
What automotive qualification does TPS628503QDRLRQ1 carry, and what temperature range does it support?
The TPS628503QDRLRQ1 is AEC-Q100 Grade 1 qualified, supporting an operating temperature range of -40°C to 125°C. This qualification level covers the majority of under-hood and passenger compartment applications where temperature cycling and long-term reliability are mandatory requirements in automotive designs.
How does PFM control in TPS628503QDRLRQ1 benefit low-power automotive standby circuits?
In PFM (Pulse Frequency Modulation) mode, the TPS628503QDRLRQ1 skips switching cycles at light loads, reducing switching losses and quiescent current below 20 µA. This is critical for always-on automotive subsystems such as telematics control units or keyless entry receivers that must stay powered for extended periods without draining the 12V vehicle battery.
Can TPS628503QDRLRQ1 supply a 1.8V rail from a 3.3V input in an ADAS sensor module?
Yes. With a 2.7V to 6V input range and adjustable output voltage down to 0.6V, the TPS628503QDRLRQ1 can easily regulate 1.8V from a 3.3V rail while delivering up to 3A. Its current-mode PWM control ensures fast transient response within 50 µs, keeping the 1.8V rail stable when ADAS processors switch between active and sleep states.
How does the SOT583 package size of TPS628503QDRLRQ1 compare to standard SO-8 alternatives for automotive buck converters?
The 8-pin SOT-5x3 (SOT583) package of TPS628503QDRLRQ1 measures approximately 2 mm × 2 mm, compared to a standard SO-8 package footprint of roughly 6 mm × 5 mm. This 85% reduction in board area makes it suitable for compact automotive camera modules or multi-rail ADAS boards where every square millimeter counts.
