Product Overview

LTC3406B is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. The 2.5V to 5.5V input voltage range makes the device 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. It is widely used in application such as cellular telephones, personal information appliances, wireless and DSL modems, digital still cameras, MP3 players, portable Instruments etc.
  • 600mA output current at VIN = 3V
  • Input voltage range is 2.5V to 5.5V
  • Low quiescent current is 300µA typical
  • Regulated feedback voltage is 0.6V typical
  • Shutdown mode (supply current) is 1µA maximum at (VRUN = 0V, VIN = 4.2V)
  • Current mode operation for excellent line and load transient response
  • Overtemperature protected
  • Peak inductor current is 1A typical
  • Operating temperature is -40°C to 85°C
  • Package style is 5-lead plastic TSOT-23
