Frequently Asked Questions
What is the quiescent current of the LT8620HMSE#PBF and why does it matter for battery applications?
The LT8620HMSE#PBF has an ultralow quiescent current of just 2.5µA, which dramatically extends battery life in standby-heavy designs. For a 1000 mAh battery with a 10µA total standby draw, this translates to over 4 years of shelf life, making it ideal for IoT sensors and automotive keep-alive circuits operating from 3.4V to 65V.
Which industrial or automotive voltage rails can the LT8620HMSE#PBF directly regulate from?
The LT8620HMSE#PBF accepts input voltages from 3.4V to 65V, allowing direct regulation from 12V automotive rails, 24V industrial bus, and 48V telecom or EV auxiliary rails. Its 2A output current and synchronous rectification deliver efficiencies above 90% across these input ranges without external diodes.
How does current-mode PWM control in the LT8620HMSE#PBF improve transient response compared to voltage-mode regulators?
Current-mode PWM control in the LT8620HMSE#PBF senses inductor current each switching cycle, providing inherent cycle-by-cycle current limiting and faster load-transient response than voltage-mode designs. This results in tighter output voltage regulation, typically within ±1%, and simplifies loop compensation for output capacitors in the 10µF to 100µF range.
What package does LT8620HMSE#PBF use and what thermal constraints apply in PCB layout?
The LT8620HMSE#PBF uses a 16-pin Small Outline (MSOP-16E) exposed-pad package. The exposed pad must be soldered to a ground plane to achieve the rated 2A continuous output; without the pad connection, thermal resistance rises and the device derates significantly above 25°C ambient.
