Applications
The LT8580IMS8E#TRPBF is designed for automotive lighting systems such as LED matrix drivers and OLED backlights that require a stable boosted output from a fluctuating 12 V car battery. Its wide 2.55 V to 40 V input tolerance handles cold-crank conditions and load-dump transients up to 40 V without external protection. Industrial applications such as 24 V bus-powered sensor transmitters and piezo driver supplies also benefit from its 65 V output capability in a minimal footprint.

Frequently Asked Questions
What makes the LT8580IMS8E#TRPBF suitable for automotive LED driver designs?
The LT8580IMS8E#TRPBF is AEC-Q100-qualified for automotive use, operates across -40°C to 125°C, and accepts input voltages from 2.55 V to 40 V to tolerate battery fluctuations from cold crank (down to 3 V) to load-dump transients near 40 V. Its 65 V output capability directly drives strings of 8 or more series white LEDs without a secondary converter stage.
How does current-mode PWM control in the LT8580IMS8E#TRPBF improve power supply stability?
Current-mode PWM control samples the inductor current on every switching cycle, providing inherent cycle-by-cycle current limiting and faster transient response than voltage-mode designs. For a 12 V input boosting to 48 V at 500 mA, the LT8580IMS8E#TRPBF can recover from a 200 mA load step within approximately 10 µs, maintaining output voltage regulation without overshoot on the 65 V capable rail.
Can the LT8580IMS8E#TRPBF operate from a 3.3 V microcontroller supply to generate a higher voltage rail?
Yes, the LT8580IMS8E#TRPBF starts up from inputs as low as 2.55 V, making it compatible with 3.3 V system rails common in low-power microcontrollers and embedded platforms. From a 3.3 V input it can boost to a regulated output up to 65 V at modest output current, enabling single-supply designs that generate high-voltage bias rails for op-amps, sensors, or piezo actuators from the same 3.3 V source.
