Product Overview

The LT1932ES6#PBF is a fixed frequency step-up DC/DC Converter designed to operate as a constant-current source. Because it directly regulates output current, the LT1932 is ideal for driving light emitting diodes (LEDs) whose light intensity is proportional to the current passing through it, not the voltage across its terminals. With an input voltage range of 1 to 10V, the device works from a variety of input sources. It accurately regulates LED current even when the input voltage is higher than the LED voltage, greatly simplifying battery-powered designs. A single external resistor sets LED current between 5 and 40mA, which can then be easily adjusted using either a DC voltage or a pulse width modulated signal. When the LT1932 is placed in shutdown, the LEDs are disconnected from the output, ensuring a quiescent current of under 1µA for the entire circuit. The device 1.2MHz switching frequency permits the use of tiny, low profile chip inductors and capacitors to minimize footprint.
  • Up to 80% efficiency

  • Disconnects LEDs in shutdown
  • Uses tiny ceramic capacitors
  • Uses tiny 1mm-tall inductors
  • Regulates current even when VIN > VOUT
  • Operates with VIN as low as 1V
