Product Overview

The LTC3406ABES5#TRMPBF is a high-efficiency monolithic synchronous Buck Regulator using a constant frequency and current-mode architecture. Supply current with no load is 200µA, dropping to <1µA in shutdown. The 2.5 to 5.5V input voltage range makes the LTC3406AB ideally suited for single Li-ion battery-powered applications. 100% duty cycle provides low dropout operation, extending battery run time in portable systems. PWM pulse skipping mode operation provides very low output ripple voltage for noise sensitive applications. Refer to LTC3406A for applications that require Burst Mode® operation. 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
  • Internal soft-start limits inrush current
  • Current-mode operation for excellent line and load transient response
  • Over-temperature protection
  • Up to 96% high efficiency
  • ±2% Output voltage accuracy

Applications

Consumer Electronics, Sensing & Instrumentation, Wireless, Communications & Networking, Portable Devices
