Product Overview

The LTC1779ES6#TRMPBF is a constant frequency current-mode step-down DC-to-DC Converter for use with scanners. The part operates with a 2.5 to 9.8V input and can provide up to 250mA of output current. Current-mode control provides excellent AC and DC load and line regulation. The device incorporates an accurate undervoltage lockout feature that shuts down the LTC1779 when the input voltage falls below 2V. The LTC1779 boasts a ±2.5% output voltage accuracy and consumes only 135µA of quiescent current. For applications where efficiency is a prime consideration, the LTC1779 is configured for Burst Mode® operation, which enhances efficiency at low output current. To further maximize the life of a battery source, the internal P-channel MOSFET is turned on continuously in dropout (100% duty cycle). In shutdown, the device draws a mere 8µA. High constant operating frequency of 550kHz allows the use of a small external inductor.
  • Current-mode operation for excellent line and load transient response
  • Up to 94% high efficiency
  • 0.8V Reference allows low output voltage
  • ±2.5% Reference accuracy
