Description

General part information

LTC3405A-1.375 Series

The LTC3405A is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. Supply current during operation is only 20µA and drops to <1µA in shutdown. The 2.5V to5.5V input voltage range makes the LTC3405A ideally suited for single Li-Ion battery-powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems.Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductors and capacitors.The LTC3405A is specifically designed to work well with ceramic output capacitors, achieving very low output voltage ripple and a small PCB footprint.The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode. Low output voltages are easily supported with the 0.8V feedback reference voltage. The LTC3405A is available in a low profile (1mm) ThinSOT package.For fixed 1.5V and 1.8V output versions, refer to theLTC3405A-1.5/LTC3405A-1.8 data sheet.Protected by U.S. Patents, including 6580258, 5481178.VoutFeaturesLTC3405Adj.-LTC3405AAdj.Stable With All Ceramic CapsLTC3405A-1.3751.375VStable With All Ceramic CapsLTC3405A-1.51.5VStable With All Ceramic CapsLTC3405A-1.81.8VStable With All Ceramic CapsApplicationsCellular TelephonesPersonal Information AppliancesWireless and DSL ModemsDigital Still CamerasMP3 PlayersPortable Instruments
