Description

General part information

LTC3406-1.2 Series

The LTC3406B 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 with no load is 300µA and drops to <1µA in shutdown. The 2.5V 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. The LTC3406B is available in a low profile (1mm) ThinSOT package. Refer to LTC3406 for applications that require Burst Mode®operation.VOUTFSWFeaturesLTC3406Adj.1.5MHzBurst ModeLTC3406-1.21.2V1.5MHzBurst ModeLTC3406-1.51.5V1.5MHzBurst ModeLTC3406-1.81.8V1.5MHzBurst ModeLTC3406BAdj1.5MHzBurst 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
