LM2655 2.5A High Efficiency Synchronous Switching Regulator April 2005 2.5A High Efficiency Synchronous Switching Regulator General Description The LM2655 is a current-mode controlled PWM step-down switching regulator. It has the unique ability to operate in synchronous or asynchronous mode. This gives the designer flexibility to choose between the high efficiency of synchronous operation, or the low solution cost of asynchronous operation. Along with flexibility, the LM2655 offers high power density with the small footprint of a TSSOP-16 package. High efficiency (>90%) is obtained through the use of an internal low ON-resistance (33mΩ) MOSFET, and an external N-Channel MOSFET....
