What are the key features of LM5010AMHE/NOPB?
- Ultra-wide 6 V to 75 V input range covering 12 V, 24 V, and 48 V industrial bus rails in a single design
- Constant on-time control for fast transient response and stable operation without external loop compensation
- 1 A output current with -40°C to 150°C operating range suitable for automotive and high-temperature industrial applications
What is LM5010AMHE/NOPB used for?
The LM5010AMHE/NOPB is designed for industrial power conversion where the input bus can range from 12 V to 48 V, including factory automation equipment, building management systems, and automotive 48 V mild-hybrid power rails. Its constant on-time architecture simplifies loop compensation and enables fast load-transient recovery without requiring precise external frequency components. The wide -40°C to 150°C temperature range makes it suitable for under-hood automotive regulators, outdoor industrial controllers, and harsh-environment instrumentation.

Frequently Asked Questions
What input voltage range does the LM5010AMHE/NOPB support, and which industrial bus standards does this cover?
The LM5010AMHE/NOPB accepts input voltages from 6 V minimum to 75 V maximum, with a nominal design point of 48 V. This wide range covers 12 V, 24 V, and 48 V industrial bus standards used in factory automation, building control, and telecom power architectures in a single hardware design without component changes.
How does constant on-time control in the LM5010AMHE/NOPB simplify PCB design compared to fixed-frequency PWM regulators?
Constant on-time control eliminates the need for precise external compensation networks because the on-time is set by a single resistor. Fixed-frequency current-mode PWM converters require an RC compensation network matched to the power stage poles and zeros. By removing this requirement, the LM5010AMHE/NOPB reduces component count, shortens design time, and improves stability across a wide range of output capacitor types including ceramic capacitors with near-zero ESR.
What is the maximum operating junction temperature of the LM5010AMHE/NOPB, and why does this matter for automotive designs?
The LM5010AMHE/NOPB is rated for operation from -40°C to 150°C junction temperature. Automotive under-hood environments can reach 125°C ambient, and with self-heating added, junction temperatures near 150°C are realistic. This rating ensures the regulator continues to operate correctly without derating output current or triggering thermal shutdown in worst-case automotive thermal scenarios.
Can the output voltage of the LM5010AMHE/NOPB be adjusted, and how is the output voltage set?
Yes, the LM5010AMHE/NOPB supports adjustable output voltage. The output is set using a resistor-divider feedback network from the output rail to the FB pin, where the reference threshold is typically 1.25 V. By selecting the appropriate ratio of two resistors, designers can program output voltages from approximately 1.25 V up to levels well below the input, with 1 A maximum continuous load current across the programmed output range.
