LM5164QDDARQ1
Brand: Texas Instruments
The LM5164QDDARQ1 is the AEC-Q100 automotive-qualified member of the LM5164 family: a 100 V input, 1 A synchronous buck converter with ultra-low quiescent current and a COT control architecture. Its integrated high-side and low-side MOSFETs remove the external Schottky diode, and its -40°C to +150°C rating makes it a drop-in choice for 48 V automotive battery and MHEV/EV rails.

Power Features & Applications
- AEC-Q100 automotive qualification (Q1 suffix) fits 48V battery and MHEV/EV rails
- 100 V input rating covers wide automotive bus transients without external surge suppression
- Synchronous architecture integrates low-side MOSFET, eliminating the external Schottky diode
- 1 A output current suits low-to-moderate automotive point-of-load rails
- Ultra-low IQ (10.5 µA no-load, 3 µA shutdown) cuts standby draw in always-on systems
- Adjustable switching frequency up to 1 MHz and COT control for fast load/line transient response
- -40°C to +150°C rating suits high-ambient under-hood-adjacent enclosures
