LвЂ‰DESIGN FEATURES Monolithic Synchronous Step-Down
Regulator Sources 3A or Sinks 1.5A
in TSSOP or 3mm Г— 4mm QFN
by Genesia Bertelle Introduction Design Versatility
Depending on the application requirements, a designer can either prioritize
light load efficiency or minimize supply noise by choosing from three light
load operating modes: Burst Mode
operation, pulse-skipping, or forced
continuous modes. Burst Mode operation provides high efficiency over
the entire load range by reducing gate
charge losses at light loads. Burst
Mode operation is an efficient solution
for low current applications, but in
some applications noise suppression
is a higher priority. Forced continuous
operation, though not as efficient as
Burst Mode operation at light loads,
maintains a constant switching frequency, making it easier to reduce
