Description
PM6685 is a dual step-down controller specifically
designed to provide extremely high efficiency
conversion with loss-less 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. The pulse skipping technique
increases efficiency for very light loads. Moreover,
a minimum switching frequency of 33kHz is
selectable in order to avoid audio noise issues.
The PM6685 provides a selectable switching
frequency, allowing either 200kHz/300kHz,
300kHz/400kHz, or 400kHz/500kHz operation of
the 5V/3.3V switching sections.
