ETA3655

5A, 2MHz ADI Controlled Output Synchronous Step-Down Converter

DESCRIPTION

FEATURES



ADI Dynamic Output Control

The ETA3655 is a high-efficiency, DC-to-DC step-down

switching regulator, capable of delivering up to 5A of

pulse load. It integrates an ADI interface that dynamically

scales the output voltages on demand. The DCDC control

block belongs to a new breed of high frequency

synchronous Step-Down converter that combines the

advantages of voltage mode control and Constant-On-

Time control. Its adaptive Constant-On-Time control

dynamically changes switch on time to achieve a constant

switching frequency. It does not have the minimum on-

time constrain normally a fixed-frequency current mode

Step-down requires, allowing it to go down to very low

duty ratio without affecting loop stability. The voltage

mode nature also provides a more superior load

transient response and a seamless transition from PFM

to PWM modes. Cycle-by-cycle current limit provides

output short-circuit protection and an input OVP function

guards ETA3655 against possible input voltage surge.

ETA3655 is housed in a 2mm x 1.6mm CSP-20 Package.
