PM6680 6680 ,No Rsense dual step-down controller with adjustable voltages for notebook system power

PM6680 is a dual step-down controller   specifically designed to provide extremely high efficiency conversion, with lossless current sensing technique. The constant on-time  architecture assures fast load transient response and the embedded voltage feed-forward provides nearly constant switching frequency operation. An embedded integrator control loop compensates the DC voltage error due to the output ripple. Pulse skipping technique increases efficiency at very light load. Moreover a minimum switching frequency of 33kHz is selectable to avoid audio noise issues. The PM6680 provides a selectable switching frequency, allowing three different values of switching frequencies for the two switching sections. The output voltages OUT1 and OUT2 can be adjusted from 0.9 V to 5.5 V
