Description
General part information
LTC3406-1.8 Series
The LTC3406 is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. The device is available in an adjustable version and fixed output voltages of 1.5V 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. The LTC3406 is available in a low profile (1mm) ThinSOT package.Protected by U.S. Patents, including 6580258, 5481178.VoutFswFeaturesLTC3406Adj.1.5MHzBurst ModeLTC3406-1.21.2V1.5MHzBurst ModeLTC3406-1.51.5V1.5MHzBurst ModeLTC3406-1.81.8V1.5MHzBurst ModeLTC3406BAdj.1.5MHzBurst Mode DisabledLTC3406B-1.21.2V1.5MHzBurst Mode DisabledLTC3406B-2Adj.2.25MHzBurst Mode DisabledLTC3406AAdj.1.5MHzLow Ripple Burst ModeLTC3406ABAdj.1.5MHzBurst Mode DisabledLTC3406AB-2Adj.2.25MHzBurst Mode DisabledApplicationsCellular TelephonesPersonal Information AppliancesWireless and DSL ModemsDigital Still CamerasMP3 PlayersPortable Instruments
