What are the key features of LTC3621IMS8E#PBF?
- 2.7V to 17V input range with 1A synchronous step-down output covering 0.6V to 17V suits diverse automotive and industrial rails
- Current-mode control with pulse skip mode delivers high efficiency at light loads, critical for always-on automotive ECU subsystems
- Automotive-qualified 8-pin MSOP-EP (S-PDSO-G8) package minimizes PCB footprint in space-constrained vehicular electronics
What is LTC3621IMS8E#PBF used for?
The LTC3621IMS8E#PBF is designed for automotive point-of-load DC-DC conversion, powering microcontrollers, sensors, and communication ICs from 12V or 5V vehicle bus rails. Its 2.7V to 17V input flexibility and 0.6V to 17V adjustable output make it suitable for always-on automotive subsystems such as keyless entry modules, telematics units, and ADAS sensor power rails. Pulse skip mode operation minimizes quiescent current in standby-critical automotive designs.

Frequently Asked Questions
What input and output voltage range does the LTC3621IMS8E#PBF cover for automotive DC-DC conversion?
The LTC3621IMS8E#PBF accepts input voltages from 2.7V to 17V with a nominal 12V input, and its output is adjustable from 0.6V to 17V at up to 1A. This range covers common automotive point-of-load requirements including 3.3V, 1.8V, and 1.2V rails for microcontrollers, FPGAs, and communication ICs powered from 12V vehicle bus.
How does pulse skip mode in LTC3621IMS8E#PBF benefit always-on automotive subsystems with strict quiescent current budgets?
Pulse skip mode in the LTC3621IMS8E#PBF reduces switching activity at light loads, dramatically lowering quiescent current consumption compared to forced continuous conduction mode. In always-on automotive applications such as keyless entry receivers and sleep-mode telematics units operating from a 12V battery, this improves standby efficiency and extends battery life during vehicle-off periods.
Can LTC3621IMS8E#PBF power a 3.3V microcontroller rail from a 12V automotive bus with enough current headroom?
Yes, the LTC3621IMS8E#PBF can step down a 12V automotive bus to a regulated 3.3V output at up to 1A using current-mode synchronous regulation. The 1A output capacity provides ample headroom for automotive microcontrollers consuming 50 mA to 400 mA, with margin for peripheral loads such as CAN transceivers, LIN drivers, and onboard sensors in ECU designs.
