Key Features
- Ultra-low 2.5 µA quiescent current in Burst Mode extends battery life in always-on IoT and automotive keep-alive circuits
- Wide 3.2 V to 42 V input range covers automotive 12 V/24 V batteries including cold-crank and load-dump transients
- 3.5 A continuous output current in a compact 16-pin MSOP-EP package enables dense multi-rail power designs
- Current-mode control with internal compensation reduces external component count and simplifies loop design
Applications
LT8610AXMSE#TRPBF is an ideal choice for automotive infotainment and ADAS sub-system power rails that must survive 42 V load-dump transients while drawing under 3 µA from the battery during vehicle-off keep-alive mode. Its wide input range and Burst Mode efficiency make it equally useful in industrial field instruments powered from unregulated 24 V rails where heat dissipation is constrained. Always-on IoT gateway designs also employ it to step down from 12 V or 24 V bus voltages to 3.3 V or 5 V at 3.5 A with minimal standby power drain.

Frequently Asked Questions
What is the quiescent current of LT8610AXMSE#TRPBF in Burst Mode and why does it matter for automotive keep-alive designs?
LT8610AXMSE#TRPBF draws only 2.5 µA of quiescent current in Burst Mode operation. In automotive keep-alive circuits that remain powered for weeks while the vehicle is parked, 2.5 µA from a 60 Ah battery represents less than 0.001% capacity loss per day, extending the period between required recharges compared with regulators drawing 50 µA to 200 µA in standby.
Which input voltage transients can LT8610AXMSE#TRPBF withstand in a 12 V automotive environment?
LT8610AXMSE#TRPBF accepts input voltages up to 42 V, comfortably covering the 40 V load-dump transients specified in ISO 7637 for 12 V automotive systems. It also handles 24 V truck battery systems and the 36 V cold-crank recovery spikes seen in start-stop vehicles, eliminating the need for a separate transient-voltage suppressor clamp in most automotive power-tree designs.
How much output current can LT8610AXMSE#TRPBF deliver continuously, and what thermal management is needed in a compact enclosure?
LT8610AXMSE#TRPBF provides 3.5 A continuous output current. With a 12 V input and 3.3 V output at 3.5 A load the synchronous regulator operates at approximately 88% efficiency, dissipating roughly 1.1 W in the package. The exposed metal pad on the 16-pin MSOP-EP must be soldered to a PCB copper pour of at least 1 cm² to keep junction temperature below 125°C in still-air conditions at 85°C ambient.
When does LT8610AXMSE#TRPBF offer a meaningful efficiency advantage over LT8610XMSE in light-load IoT applications?
The 'A' variant LT8610AXMSE#TRPBF improves light-load efficiency by refining the Burst Mode threshold, reducing losses at currents below 50 mA where the base LT8610XMSE shows higher ripple-versus-efficiency trade-offs. For IoT sensors that spend 95% of their time in sleep mode drawing under 10 mA from a 3.3 V rail, this translates to several months of additional battery runtime from a 3 Ah lithium primary cell.
