|
The LM2640 is a dual step-down power supply controller intended for application in notebook personal computers and other battery-powered equipment.
Fixed-frequency synchronous drive of logic-level Nchannel power MOSFETs is combined with an optional pulse-skipping mode to achieve ultra efficient power conversion over a 1000:1 load current range.
The pulse-skipping mode can be disabled in favor of fixed-frequency operation regardless of the load current level.
