Description

General part information

LTC3403 Series

The LTC3403 is a high efficiency monolithic synchronous buck regulator optimized for WCDMA power amplifier applications. The output voltage can be dynamically programmed from 0.3V to 3.5V. At VOUT> 3.6V an internal bypass P-channel MOSFET connects VOUTdirectly to VIN, eliminating power loss through the inductor. Selectable forced continuous mode enables fast VOUTresponse to the controlling input.Supply current is only 20µA in Burst Mode®operation and drops to <1µA in shutdown. The 2.5V to 5V input voltage range makes the LTC3403 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 internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode.The LTC3403 is available in a low profile 8-lead 3mm x 3mm DFN package.ApplicationsWCDMA Cell Phone Power AmplifiersWireless Modems
