1.5MHz, 300mA Synchronous Step-Down Regulator In ThinSOT

The LTC3405 is a high efficiency monolithic synchro- nous buck Regulator using a constant frequency, current mode architecture. Supply current during operation is only 20A and drops to <1A in shutdown. The 2.5V to 5.5V input voltage range makes the LTC3405 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 Low output voltages are easily supported with the 0.8V feed- back reference voltage. The LTC3405 is available in a low profile (1mm) ThinSOT package. For new designs, refer to the LTC3405A data sheet. For fixed 1.5V and 1.8V output versions, refer to the LTC3405A-1.5/LTC3405A-1.8 data sheet. By Linear Technology Corporation
