Description

The DIO60010/A is a high-efficiency synchronous

step-down DC-DC regulator. The DIO60010/A can

achieve up to 1 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(COT) control provides a fast

transient response and eases loop stabilization. The

DIO60010 includes an automatically entered power

save mode to maintain high efficiency down to very

light loads for extending the system battery run-time.

The DIO60010A runs in Forced PWM maintaining a

continuous conduction mode to ensure the least

ripple in the output voltage and a quasi-fixed

switching frequency. The device features a

Power-good signal.

The DIO60010/A is ideal for a wide range of

applications, including portable navigation devices,

set top boxes and media players.
