ETA3527

2MHz, 2A, COT Synchronous Step-down Converter in SOT563

DESCRIPTION

FEATURES

The ETA3527 is a high-efficiency, DC-to-DC step-down

switching regulator, capable of delivering up to 2Aof output

current. The devices operate from an input voltage range

of 2.5V to 6.0V and provide output voltages from 0.6V to

VIN, making the ETA3527 ideal for low voltage power

conversions. ETA3527 adopts an adaptive COT control

scheme that enables very fast transient response and

provides a very smooth transition when the output varies

from light load to heavy load. The adaptive COT control

also maintains a constant switching frequency across line

and load. Running at a fixed frequency of 2MHz allows the

use of small inductance value and low DCR inductors,

thereby achieving a higher efficiency. Other external

components, such as ceramic input and output caps, can

also be small due to higher switching frequency, while

maintaining exceptional low-noise output voltages.

Internal soft-start control circuitry reduces inrush current.

Short-circuit and thermal-overload protection improves
