DESCRIPTION
The
TPS6420x
are
nonsynchronous
step-down
controllers that are ideally suited for systems powered
from a 5-V or 3.3-V bus or for applications powered from
a 1-cell Li-Ion battery or from a 2- to 4-cell NiCd, NiMH, or
alkaline battery. These step-down controllers drive an
external P-channel MOSFET allowing design flexibility. To
achieve highest efficiency over a wide load current range,
this controller uses a minimum on time, minimum off time
control scheme and consumes only 20-
A quiescent
current. The minimum on time of typically 600 ns
(TPS64203) allows the use of small inductors and
capacitors. When disabled, the current consumption is
reduced to less than 1
A. The TPS6420x is available in
the 6-pin SOT23 (DBV) package and operates over a free
air temperature range of 40
°C to 85°C.
