Key Features
- 2.5 µA ultra-low quiescent current in Burst Mode operation for maximum battery runtime in always-on IoT sensor nodes
- 42 V maximum input rating with 3 V to 42 V operating range, covering automotive 12 V/24 V and industrial 36 V rails with transient protection
- 3.5 A continuous output current at up to 94% efficiency using integrated synchronous rectifier eliminating external Schottky diode
- Fixed 1 MHz switching frequency minimizes inductor and capacitor size for compact solution footprint on dense PCBs
- Current-mode PWM control with fast load-transient response and programmable soft-start for safe power sequencing
Applications
The LT8610ACEMSE-1#PBF is widely used in automotive always-on subsystems such as GPS trackers, dashcams, and telematics units that must maintain sub-3 µA standby current while withstanding 42 V load dumps on a 12 V vehicle battery. Industrial IoT gateway boards and wireless sensor nodes powered from 24 V to 36 V supply rails rely on its Burst Mode efficiency to extend unattended field operation, delivering 3.5 A to local processors and radios without a heatsink. Embedded computing modules and SBC power stages running from 12 V rails also benefit from its 1 MHz fixed frequency, which pushes switching noise above the AM radio band and simplifies EMI filter design.

Frequently Asked Questions
What input voltage range and quiescent current does LT8610ACEMSE-1#PBF support for automotive and industrial applications?
The LT8610ACEMSE-1#PBF operates from 3 V to 42 V input, covering 12 V and 24 V automotive battery rails including 42 V cold-crank and load-dump transients. In Burst Mode operation it draws only 2.5 µA quiescent current, allowing always-on embedded systems such as GPS trackers and telematics modules to remain active from a parked vehicle battery for weeks without draining it below 10.5 V start threshold.
Which automotive and IoT applications are best served by deploying LT8610ACEMSE-1#PBF as the main power regulator?
Automotive dashcams, GPS fleet trackers, and OBD-II data loggers that must survive 42 V load-dump transients while consuming under 3 µA in standby are ideal targets for this regulator. Industrial IoT nodes powered from 24 V to 36 V field bus rails and wireless sensor networks requiring 3.5 A peak output for RF transmission bursts also benefit from its synchronous rectifier achieving over 90% efficiency, eliminating the need for an external Schottky diode and simplifying thermal management on compact PCBs.
How does LT8610ACEMSE-1#PBF compare to LT8610 when selecting a low-quiescent buck regulator for a 24 V panel PC?
The LT8610ACEMSE-1#PBF is the automotive-grade and tighter accuracy version of the LT8610 family, specifying a 1% output voltage accuracy over -40°C to 125°C versus 1.5% for some standard grades. For a 24 V industrial panel PC requiring 5 V at 3 A with guaranteed output accuracy across temperature, the ACEMSE variant ensures the regulated output stays within ±50 mV of the 5 V setpoint throughout its operating lifetime, whereas a lower-grade part may drift beyond this at temperature extremes.
What inductor and output capacitor values are recommended for a 12 V to 5 V, 3 A design with LT8610ACEMSE-1#PBF at 1 MHz?
At 1 MHz switching frequency with a 12 V input and 5 V output, the LT8610 datasheet recommends a 4.7 µH inductor with DC resistance below 30 mΩ and a 22 µF to 47 µF ceramic output capacitor. This combination achieves peak-to-peak output ripple below 20 mV and a solution footprint under 120 mm², with the 1 MHz frequency keeping the inductor height below 2 mm for use in low-profile enclosures. Adding a 10 µF input ceramic capacitor close to the VIN pin limits input voltage ringing during fast switching transitions.
