What are the key features of LT3489EMS8E?
- 2 MHz switching frequency reduces external inductor and capacitor size for compact boost converter PCB layouts
- 2.5 A internal switch with current-mode PWM control delivers fast transient response and cycle-by-cycle current limiting
- Adjustable soft-start limits inrush current at power-up, protecting batteries and USB ports in portable designs
What is LT3489EMS8E used for?
The LT3489EMS8E is ideal for battery-powered portable equipment, handheld instruments, and LED driver circuits requiring a regulated boosted output from a 2.6 V to 16 V supply. Its 2 MHz switching frequency minimizes external passive component size, making it well suited for space-constrained designs. The adjustable soft-start function also makes it a strong fit for USB-powered and current-limited input source applications.
