... The lower current limit allows the use of a physically smaller inductor in space-sensitive applications. PFM Control Scheme A key feature of the SS6610 series is a unique minimum-off-time, constant-on-time, current-limited, pulse-frequency-modulation (PFM) control scheme (see BLOCK DIAGRAM) with ultra-low quiescent Rev ...

... PCB Layout and Grounding Since the SS6610/11’s switching frequency can range up to 500kHz, the SS6610/11 can be very sensitive. Careful printed circuit layout is im- portant for minimizing ground bounce and noise. The OUT pin should be as clear as possible, and the GND pin should be placed close to the ground plane. Keep the IC’ ...
