What are the key features of LTC3621EMS8E-2#PBF?
- Wide 2.7 V to 17 V input range covers automotive 12 V bus with full load-dump transient margin
- 1 A synchronous step-down with current-mode control and pulse-skip mode for high light-load efficiency
- Compact 8-pin MSOP-EP package reduces solution footprint to under 50 mm² with minimal external components
What is LTC3621EMS8E-2#PBF used for?
The LTC3621EMS8E-2#PBF is well suited for automotive subsystems requiring a robust step-down regulator from a 12 V rail, such as infotainment modules, ADAS sensor supplies, and body-control units demanding stable 0.6 V to 17 V outputs at up to 1 A. Its current-mode control with pulse-skip mode maintains high efficiency across the full load range, benefiting battery-powered or always-on ECU designs. The wide input range also makes it useful in industrial 12 V and 24 V distribution systems where transient voltages exceed 17 V momentarily.

Frequently Asked Questions
What input voltage range does the LTC3621EMS8E-2#PBF support for automotive 12 V systems?
The LTC3621EMS8E-2#PBF accepts an input voltage from 2.7 V to 17 V, comfortably covering a nominal 12 V automotive bus including cold-crank dips and mild load-dump transients. This range accommodates battery voltages down to 2.7 V during deep discharge, making it reliable across diverse automotive operating conditions with a maximum 1 A output current.
How does the pulse-skip mode improve efficiency in low-current automotive standby states?
In pulse-skip mode, the LTC3621EMS8E-2#PBF skips switching cycles when the output load is light, reducing switching losses and maintaining efficiency above 80% at currents below 10 mA. This is critical for always-on automotive circuits such as body-control modules that draw only a few milliamps during vehicle-off standby, where continuous PWM switching would waste battery charge over hours of idle time.
Is the LTC3621EMS8E-2#PBF a suitable drop-in replacement for the LTC3621EMS8E-5 in a 5 V output design?
The LTC3621EMS8E-2#PBF is the 2 V variant, meaning its internal feedback reference is tuned for a 2 V output with standard resistor dividers, whereas the LTC3621EMS8E-5 targets a 5 V output. Both share the same 8-pin MSOP package and 2.7 V to 17 V input range with 1 A output, so pin placement is identical, but the external resistor divider values must be recalculated to achieve 5 V with the -2 variant before it can serve as a replacement.
