What are the key features of LM34917ATL?
- Wide input voltage range of 8 V to 33 V with current-mode control supports both buck and boost conversion in a single device
- Peak output current up to 1.55 A with dual-switch topology enables high-efficiency power delivery for demanding loads
- Compact 12-pin BGA package minimizes PCB footprint for space-constrained automotive and industrial power supply designs
What is LM34917ATL used for?
The LM34917ATL is used in automotive and industrial power management designs requiring a wide input voltage range from 8 V to 33 V, such as car infotainment power rails, 12 V/24 V industrial bus regulators, and battery-powered equipment. Its dual-switch buck/boost topology maintains a stable output even when input voltage varies above and below the output, making it ideal for battery backup circuits. The 12-pin BGA package supports compact DC-DC converter modules in space-limited applications.

Frequently Asked Questions
What input and output voltage range does the LM34917ATL support and why is this useful for automotive designs?
The LM34917ATL accepts input voltages from 8 V to 33 V and can deliver a regulated output with up to 1.55 A load current. This range covers standard 12 V automotive batteries including cold-crank and load-dump transients, making it suitable for car audio, infotainment, and telematics power rails.
How does the current-mode control of LM34917ATL improve transient response compared to voltage-mode regulators?
Current-mode control in the LM34917ATL senses inductor current on a cycle-by-cycle basis, enabling faster load transient response typically within a few microseconds at 1.55 A maximum output. This inner current loop also provides inherent overcurrent limiting and simplifies compensation, reducing external component count.
In which scenario would you choose LM34917ATL over a simple buck converter for a 12 V to 5 V industrial rail?
When the input supply can swing above and below the 5 V output—such as in a 12 V industrial bus with holdup capacitors dropping to 4 V during fault—a buck/boost topology like LM34917ATL is necessary. A pure buck converter would lose regulation below 5 V input, while the LM34917ATL maintains output from 8 V to 33 V input with up to 1.55 A continuous output.
