Frequently Asked Questions
What input voltage range does the LM5010AQ1MH support for automotive and industrial applications?
The LM5010AQ1MH operates from a 6 V to 75 V input range, with a nominal design target of 48 V. This enables direct step-down conversion from 12 V, 24 V, and 48 V automotive battery or industrial bus rails to lower regulated voltages without the need for a pre-regulator stage.
What is the maximum output current of the LM5010AQ1MH and what loads can it supply?
The LM5010AQ1MH delivers up to 1.5 A continuous output current, sufficient to power microcontrollers, FPGAs, CAN transceivers, and analog sensor circuits in automotive body control and industrial node designs. The internal gate driver and control circuitry are optimized to maintain regulation across this full 1.5 A load range.
Is the LM5010AQ1MH qualified for automotive use and what temperature range does it support?
The LM5010AQ1MH carries the AEC-Q100 automotive qualification, with operation across the extended automotive temperature range of -40°C to 125°C. This makes it suitable for under-the-hood applications such as engine control units, transmission controllers, and EV battery management systems exposed to extreme thermal conditions.
What control topology does the LM5010AQ1MH use and how does this affect converter design?
The LM5010AQ1MH uses voltage-mode PWM control with an adjustable switching frequency range, allowing designers to balance switching losses, inductor size, and EMI signature. Voltage-mode control simplifies loop compensation and is well-suited for applications with relatively stable input voltage such as regulated 48 V bus architectures.
What package does the LM5010AQ1MH use and how does it fit into a board layout?
The LM5010AQ1MH is housed in a 14-pin TSSOP package, measuring approximately 5 mm x 4.4 mm. Its compact footprint and standard TSSOP pitch simplify PCB routing for step-down power stages in space-limited automotive control modules and industrial PCB assemblies requiring up to 1.5 A regulated output.
