Product Overview

The LTC3525ESC6-3.3#TRMPBF is a 400mA micropower synchronous Step-up DC/DC Converter with output disconnect that can start up with an input as low as 0.85V. They offer a compact, high efficiency alternative to charge pumps in single cell or dual cell alkaline or Li-ion applications. Only three small external components are required. The device includes a 0.5R N-channel MOSFET switch and a 0.8R P-channel synchronous rectifier. Peak switch current ranges from 150 to 400mA, depending on load, providing enhanced efficiency. Quiescent current is an ultralow 7µA, maximizing battery life in portable applications. Other features include <1µA shutdown current, Anti-ringing control and thermal shutdown.
  • Up to 95% efficiency
  • Output disconnect and inrush current limit
  • Fixed output voltages of 3, 3.3 or 5V
  • Delivers 65mA at 3V from a 1V input
  • Delivers 60mA at 3.3V from a 1V input or 140mA at 3.3V from a 1.8V input
  • Delivers 175mA at 5V from a 3V input
  • Burst Mode® operation (IQ = 7µA)
  • Only three external components
  • VIN > VOUT operation
  • <1µA Shutdown current
  • Anti-ringing control
  • Short-circuit and over-temperature protection
