Product Overview

The LT1613CS5#TRMPBF is a 1.4MHz single cell DC/DC Converter intended for small, low power applications. It operates from an input voltage as low as 1.1V and switches at 1.4MHz, allowing the use of tiny, low cost capacitors and inductors 2mm or less in height. Multiple output power supplies can now use a separate regulator for each output voltage, replacing cumbersome quasi-regulated approaches using a single regulator and a custom transformer. A constant frequency internally compensated current mode PWM architecture results in low predictable output noise that is easy to filter. The high voltage switch is rated at 36V, making the device ideal for boost converters up to 34V as well as for Single-Ended Primary Inductance Converter (SEPIC) and flyback designs. The device can generate 5V at up to 200mA from a 3.3V supply or 5V at 175mA from four alkaline cells in a SEPIC design.
  • Uses tiny capacitors and inductor
