Key Features
- 75V input rating handles automotive 48V mild-hybrid bus, 24V commercial vehicles, and load-dump transients
- Adjustable output voltage down to 1.225V via external resistor divider for flexible MCU and sensor rail generation
- Current-mode PWM control delivers fast load transient response with inherent cycle-by-cycle current limiting
- AEC-Q100-qualified for automotive -40°C to 125°C operation in underhood and body control environments
Applications
The LM5575Q0MH/NOPB is designed for automotive power management applications requiring step-down regulation from 48V mild-hybrid, 24V truck, or 12V vehicle batteries where load-dump transients can spike above 60V. It is commonly used to power ADAS processors, body control modules, and automotive Ethernet interfaces from the vehicle battery rail without an additional pre-regulator stage. Its current-mode PWM topology and AEC-Q100 qualification make it a dependable choice for underhood and door-module designs demanding high thermal reliability.

Frequently Asked Questions
What is the absolute maximum input voltage rating of the LM5575Q0MH/NOPB and why does it matter for automotive use?
The LM5575Q0MH/NOPB accepts input voltages up to 75V, which is critical in automotive designs where ISO 7637 load-dump transients on 12V or 24V batteries can momentarily spike to 60V or higher. This tolerance eliminates the need for external transient suppressors in most vehicle applications.
How low can the LM5575Q0MH/NOPB regulate its output voltage and what sets it?
Output voltage is adjustable down to 1.225V using a resistor divider from the output node to the feedback pin, supporting core voltage rails for application processors, FPGAs, and low-voltage microcontrollers. The minimum 1.225V corresponds to the internal voltage reference, giving designers full range from 1.225V up to near the input voltage.
Which automotive subsystems most benefit from selecting LM5575Q0MH/NOPB over a lower-voltage buck regulator?
ADAS camera modules, LiDAR power boards, automotive gateway ECUs, and 48V-to-low-voltage converters all benefit because a single LM5575Q0MH/NOPB handles the full 6V to 75V input span without a two-stage pre-regulation approach, reducing BOM complexity, PCB area, and total system cost by eliminating one power stage.
