L6996 is dc-dc controller specifically designed to provide extremely high efficiency conversion for mobile advanced microprocessors.
The "constant on-time" topology assures fast load transient response. The embedded "voltage feedforward" provides nearly constant switching frequency operation.
A precise 5-bit DAC allows select output voltage from 0.6V to 1V with 25mV steps and from 1V to 1.75V with 50mV steps.
L6996 is capable of supporting CPUs VID combination changing during normal operation.
The active droop allows adjust both the output loadline slope and the zero-load output voltage.
