Product Overview

The LT1935ES5#TRMPBF is a 1.2MHz Boost DC/DC Converter with an unprecedented 2A, 40V internal switch allowing high current outputs to be generated in a small footprint. Intended for space-conscious applications, the LT1935 switches at 1.2MHz allowing the use of tiny, low profile inductors and capacitors 2mm or less in height. The NPN switch achieves a VCESAT of just 180mV at 2A independent of supply voltage, resulting in high efficiency even at maximum power levels from a 3V input. A constant frequency, internally compensated, current mode PWM architecture results in low, predictable output noise that is easy to filter. Low ESR ceramic capacitors can be used on the output, further reducing noise to the millivolt level. The high voltage switch is rated at 40V, making the device ideal for boost converters up to 38V as well as for single-ended primary inductance converter (SEPIC) and flyback designs.
  • High output voltage (up to 38V)
  • Low VCESAT switch (180mV at 2A)
  • Soft-start
  • Uses small surface mount components
  • 5V at 1A from 3.3V input
  • 12V at 600mA from 5V input
  • Low shutdown current (<1µA)
  • Pin-for-pin compatible with LT1613 and LT1930
