LTC3410ESC6#TRMPBF

LTC3410 is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. The 2.5V to 5.5V input voltage range makes the device 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 2.25MHz, allowing the use of small surface mount inductors and capacitors. It 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. It is used in application such as cellular telephones, wireless and DSL modems, digital cameras, MP3 players, portable instruments etc.
