Product Overview

The LTC3406BES5#TRMPBF is a high-efficiency monolithic synchronous Buck Regulator using a constant frequency and current-mode architecture. The device is available in an adjustable version and fixed output voltages of 1.5 and 1.8V. Supply current with no load is 300µA and drops to <1µA in shutdown. The 2.5 to 5.5V input voltage range makes the LTC3406B ideally suited for single Li-ion battery-powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems. PWM pulse skipping mode operation provides very low output ripple voltage for noise sensitive applications. 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.
  • No Schottky diode required
  • Current-mode operation for excellent line and load transient response
  • Over-temperature protection
  • Up to 96% high efficiency
  • 0.6V Reference allows low output voltage
