Key Features
- Wide 2.55 V to 40 V input range with 65 V output capability enabling boost regulation across automotive battery transients, cold-crank, and load-dump events
- Current-mode PWM control architecture providing cycle-by-cycle overcurrent protection and fast transient response in high-voltage boost applications
- Compact 8-pin MSOP with exposed thermal pad (EP) reducing thermal resistance and enabling up to multi-watt output power in a minimal PCB footprint
Applications
The LT8580EMS8E#TRPBF is designed for automotive bias supply generation, OLED/TFT display backlight drivers, and industrial sensor excitation circuits requiring boost conversion from battery or bus voltages up to 40 V to regulated outputs approaching 65 V. Its wide input range makes it well-suited for 12 V and 24 V automotive systems that must survive cold-crank sags down to 2.55 V and load-dump spikes near 40 V without dropouts. Engineers also use it in LED string drivers, piezo actuator supplies, and solenoid bias rails where high-voltage step-up with tight regulation is essential.

Frequently Asked Questions
Can LT8580EMS8E#TRPBF maintain regulated output during a 12 V automotive cold-crank event where input drops to 3 V?
Yes, the LT8580EMS8E#TRPBF operates from a minimum input of 2.55 V, well below the 3 V floor of a typical automotive cold-crank transient on a 12 V battery. Its current-mode PWM control adjusts duty cycle dynamically to sustain a regulated boost output even as input voltage sags, ensuring downstream circuits such as OLED display drivers or sensor bias rails remain powered throughout the cold-crank event.
What is the maximum output voltage achievable with LT8580EMS8E#TRPBF, and which display panel drive voltage does this enable?
The LT8580EMS8E#TRPBF supports boost output voltages up to 65 V, sufficient to drive OLED panel bias rails typically requiring 40 V to 60 V or piezoelectric actuator supplies requiring 40 V to 55 V. With a 12 V automotive input, the device achieves over 5:1 voltage step-up ratio, making it a direct solution for thin-film transistor LCD gate drivers and EL backlight inverters without a separate high-voltage supply.
How does the exposed thermal pad of the 8-pin MSOP package improve thermal performance for LT8580EMS8E#TRPBF at elevated output power?
The exposed thermal pad (EP) on the MSOP-8E package conducts heat directly to the PCB copper pour, reducing the junction-to-board thermal resistance by several degrees Celsius per watt compared to a standard MSOP without an EP. For a design delivering 1 W to 2 W of output power at 65 V from a 12 V input, this lower thermal resistance keeps junction temperature within the -40°C to 125°C automotive operating range without external heatsinking.
When is LT8580EMS8E#TRPBF a more suitable boost converter than LT8580IMS8E for a 24 V automotive industrial platform?
The E-grade LT8580EMS8E#TRPBF is specified over the extended automotive temperature range of -40°C to 125°C, whereas the I-grade LT8580IMS8E is rated to 85°C. For a 24 V automotive industrial platform where under-hood or engine-bay ambient temperatures exceed 85°C, the E-grade variant ensures full-specification PWM boost regulation across the entire automotive thermal envelope without thermal derating or output accuracy degradation.
