Description
General part information
LTC3406B-1.2 Series
The LTC3406B-1.2 is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. Supply current with no load is 300µA dropping to <1µA in shutdown. The 2.5V to 5.5V input voltage range makes the LTC3406B-1.2 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. The LTC3406B-1.2 is available in a low profile (1mm) ThinSOT package.Protected by U.S. Patents including 5481178, 6580258, 6304066, 6127815, 6498466, 6611131.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
