Description

General part information

LTC3405A-1.5 Series

The LTC3405A-1.5/LTC3405A-1.8 are high efficiency monolithic synchronous buck regulators using a constant frequency, current mode architecture. Supply current during operation is only 20µA and drops to <1µA in shutdown. The 2.5V to 5.5V input voltage range makes the LTC3405A-1.5/LTC3405A-1.8 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-1.5/LTC3405A-1.8 are 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. The LTC3405A-1.5/LTC3405A-1.8 are available in a low profile (1mm) ThinSOT package.For adjustable output voltage, refer to the LTC3405A 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
