Product Overview

The LT1611CS5#TRMPBF is a current-mode DC-to-DC Converter intended for use in small and low power applications. It operates from an input voltage as low as 1.1V and switches at 1.4MHz, allowing the use of tiny, capacitors and inductors 2mm or less in height. Its small size and high switching frequency enable the complete DC/DC converter function to consume less than 0.25 square inches of PC board area. Capable of generating -5V at 150mA from a 5V supply or -5V at 100mA from a 3V supply, the LT1611 replaces non-regulated charge pump solutions in many applications. The LT1611 operates in a dual inductor inverting topology which filters the input side as well as the output side of the DC/DC converter. Fixed frequency switching ensures a clean output free from low frequency noise typically present with charge pump solutions. No load quiescent current of the LT1611 is 3mA, while in shutdown quiescent current drops to 0.5µA. The 36V switch allows VIN to VOUT differential of up to 33V.
  • Better regulation than a charge pump
