Package Information
Description
The DIO60120 is a high-efficiency synchronous
step-down DC-DC regulator. The DIO60120 can
achieve up to 2 A continuous output current from a
2.5 V to 5.5 V input voltage with excellent load and
line regulation. The output voltage can be regulated
to as low as 0.6 V.
Constant-on-time control provides a fast transient
response and eases loop stabilization. The
DIO60120 includes an automatically entered power
save mode to maintain high efficiency down to very
light loads for extending the system battery run-time.
The DIO60120 is ideal for a wide range of
applications, including portable navigation devices,
set top boxes and media players.
