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. Moreover a 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 (switchover function).
