Description

  • Typical Application for LTC3525D-3.3 - 400mA Micro-power Synchronous Step-Up DC/DC Converter with Pass Through Mode. The LTC3525D-3.3 is a high efficiency synchronous step-up DC/DC converter that can start up with an input as low as 0.85V. It offers 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 LTC3525D features a fixed output voltage of 3.3V. In shutdown, VOUT is connected to VIN through the inductor
