PM6686 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. Pulse skipping technique increases efficiency at very light load. Moreovera minimum switching frequency of 33 kHz is selectable to avoid audio noise issues. The PM6686 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 programmed to regulate 1.5 V/5 V and 1.05 V/3.3 V outputs respectively or can deliver two adjustable output voltages. An optional external charge pump can be monitored.
This device embeds a linear regulator that can provide 3.3 V/5 V or an adjustable voltage from 0.7 V to 4.5 V output. The linear regulator provides up to 100 mA output current. LDO can be bypassed with the switching regulator outputs or with an external power supply.
Please note fitting require good skills and equipment.
