What are the key features of LT3990EMSE-5#PBF?
- Ultra-low 2µA quiescent current minimizes standby power loss in always-on industrial and automotive systems
- Wide input range from 4.2V to 62V supports automotive, industrial, and high-voltage bus applications directly
- Integrated catch diodes reduce external component count and simplify PCB layout in step-down designs
- 350mA output current with current-mode PWM control delivers stable regulation and fast transient response
What is LT3990EMSE-5#PBF used for?
The LT3990EMSE-5#PBF is ideal for automotive and industrial applications requiring a small, efficient step-down regulator that operates over wide input voltage ranges up to 60V. Its 2µA quiescent current makes it an excellent choice for always-on monitoring circuits, keep-alive supplies, and battery-backed systems where idle power drain is critical. The integrated diodes and 16-pin MSOP package reduce board area and external component count in distributed power architectures.

Frequently Asked Questions
How wide is the input voltage range of the LT3990EMSE-5#PBF and which power buses does it support?
The LT3990EMSE-5#PBF accepts input voltages from 4.2V to 62V, covering 12V automotive batteries, 24V industrial rails, and 48V bus systems, making it a versatile single-chip solution across multiple power architectures.
What makes the 2µA quiescent current of LT3990EMSE-5#PBF significant for battery-powered designs?
A quiescent current of just 2µA means that in standby, a 1000mAh battery would last theoretically over 500000 hours at idle, extending battery life dramatically in always-on keep-alive and monitoring applications.
Does the LT3990EMSE-5#PBF require an external catch diode for its step-down switching operation?
No, the device integrates the catch diodes internally, eliminating the need for external Schottky diodes, reducing BOM cost, saving PCB space, and simplifying layout for the 350mA step-down converter circuit.
Which control method does LT3990EMSE-5#PBF use and how does that affect output regulation quality?
The device uses current-mode pulse width modulation (PWM) control, which provides inherent cycle-by-cycle current limiting, improved line transient response, and better stability across the 4.2V to 62V input range compared to voltage-mode control.
