Key Features
- 2 A integrated switch supporting boost, SEPIC, and inverting converter topologies in one IC
- Wide input voltage range from 2.5 V to 32 V accommodating diverse battery and supply rail designs
- Soft-start function limits inrush current during power-up, protecting sensitive loads and capacitors
- External clock synchronization pin allows alignment with system switching frequency to reduce EMI beating
Applications
LT3580MPMS8E#TRPBF is used to generate higher or inverted output voltages from low input rails in handheld instruments, LCD bias supplies, and multi-rail embedded systems. Its 2.5 V minimum input voltage makes it suitable for single-cell lithium-ion battery applications that require 5 V or 12 V outputs. The synchronization feature simplifies EMI management in noise-sensitive analog and mixed-signal boards.

Frequently Asked Questions
What is the input voltage range of LT3580MPMS8E#TRPBF and which battery chemistries does it support?
LT3580MPMS8E#TRPBF accepts input voltages from 2.5 V to 32 V, covering single-cell lithium-ion batteries at 3.7 V nominal, 3-cell NiMH packs at around 3.6 V, and regulated 12 V or 24 V industrial supply rails. This wide range allows a single design to serve portable, automotive, and industrial power conversion applications.
How does the soft-start feature of LT3580MPMS8E#TRPBF protect downstream circuits during power-up?
The soft-start function in LT3580MPMS8E#TRPBF gradually ramps the switch duty cycle from zero over a programmable interval, limiting peak inrush current to the output capacitor and load. This prevents input voltage droop when powering from weak sources and avoids overshoot stress on output capacitors rated for the output voltage.
Can LT3580MPMS8E#TRPBF generate a negative supply voltage, and what topology does it use for that?
Yes, LT3580MPMS8E#TRPBF supports an inverting converter topology using a single inductor and diode, generating a negative output voltage from a positive input. For example, from a 5 V input, it can produce -5 V or -12 V rails needed by op-amps, LCD drivers, or analog front-end circuits, using current-mode PWM control with the 2 A switch.
