Description
The LM2655 is a current-mode controlled PWM step-downandnbsp;switching regulator. it has the unique ability to operate inandnbsp;synchronous or asynchronous mode. This gives the designer flexibility to choose between the high efficiency ofandnbsp;synchronous operation, or the low solution cost of asynchronous operation. Along with flexibility, the LM2655 offers highandnbsp;power density with the small footprint of a TSSOP-16 package.
High efficiency (andgt;90%)is obtained through the use of anandnbsp;internal low ON-resistance (33mandOmega;) MOSFET, and an external N-Channel MOSFET. This feature, together with its lowandnbsp;quiescent current, makes the LM2655 an ideal fit in portableandnbsp;applications.
Integrated in the LM2655 are all the power, control, and driveandnbsp;functions for asynchronous operation. In addition, a low-sideandnbsp;driver output allows easy synchronous operation. The lCandnbsp;uses patented current sensing circuitry that eliminates theandnbsp;external current sensing resistor required by other currentmode DC-DC converters.A programmable soft-start featureandnbsp;limits start up current surges and provides a means of sequencing multiple power supplies.
