Product Overview

The LTC3406ES5-1.8#TRMPBF is a high efficiency monolithic synchronous Buck Regulator uses a constant frequency, current mode architecture. The device is available in an adjustable version and fixed output voltages of 1.5 and 1.8V. Supply current during operation is only 20µA and drops to <=1µA in shutdown. The 2.5V to 5.5V input voltage range makes the LTC3406 ideally suited for single Li-ion battery-powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems. Automatic Burst Mode® operation increases efficiency at light loads, further extending battery life. Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductors and capacitors. The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode. Low output voltages are easily supported with the 0.6V feedback reference voltage.
  • Up to 96% high efficiency
  • No Schottky diode required
  • 100% Duty cycle low dropout operation
  • Shutdown mode draws <=1µA supply current
  • Current mode operation for excellent line and load transient response
  • Overtemperature protected
