Product Overview

The LTC3458EDE#PBF is a high-efficiency fixed frequency step-up DC-to-DC Converter with true output disconnect and inrush current limiting. The LTC3458 is rated for a 7.5V output and includes a 0.3R N-channel MOSFET switch and a 0.4R P-channel MOSFET synchronous rectifier. The LTC3458 is well suited for battery-powered applications and includes programmable output voltage, switching frequency and loop compensation. The oscillator frequency can be set up to 1.5MHz or synchronized to an external clock. Quiescent current is only 15µA during Burst Mode® operation and maximizing battery life. The Burst Mode® current threshold, peak current limit and soft-start are externally programmable. Other features include <1µA shutdown current, anti-ringing control and thermal limit.
  • Inrush current limiting and output disconnect
  • Programmable automatic Burst Mode® operation
  • Current-mode control with programmable soft-start period and peak current limit
  • Up to 93% high efficiency
  • 700mA at 7V from 5V Input
