Frequently Asked Questions
What is the input voltage range supported by the LTC3621EMS8E-23.3#PBF?
The LTC3621EMS8E-23.3#PBF accepts an input voltage range of 2.7V to 17V, making it compatible with 3.3V, 5V, and 12V bus systems. This wide range supports both automotive 12V rails and lower-voltage portable applications without requiring an additional pre-regulator stage.
How much output current can the LTC3621EMS8E-23.3#PBF supply to the load?
The device can continuously supply up to 1A of output current at the fixed 3.3V output. The synchronous rectifier topology allows efficient power delivery across the full load range, and the 8-pin MSOP-EP package aids thermal dissipation for sustained 1A operation.
Which automotive designs benefit most from the pulse-skip operating mode of this regulator?
Automotive always-on subsystems such as body control modules and keyless entry transceivers, which draw less than 50 mA in standby, gain the most from pulse-skip mode because the regulator reduces switching losses and keeps quiescent current in the microamp range, extending 12V battery life during ignition-off periods.
What package does the LTC3621EMS8E-23.3#PBF use and what board area does it occupy?
It is housed in an 8-pin MSOP-EP package measuring approximately 3 mm x 3 mm, including the exposed pad. The small footprint allows integration into space-constrained PCB designs alongside microcontrollers and sensors, particularly in wearable or miniaturized industrial modules.
