ETA3451D2I Description

Short technical summary and product information.

The ETA3451D2I is a high-frequency synchronous step-down converter that combines voltage mode control and Constant-On-Time (COT) control. Its adaptive COT control dynamically adjusts the switch on-time to maintain a constant switching frequency, allowing for very low duty ratios without compromising loop stability. This design provides superior load transient response and a seamless transition between PFM and PWM modes.

 

Key features include a maximum output current of 3.5A, a feedback voltage of 0.45V, and efficiencies up to 95%. It is particularly suitable for applications requiring stable power delivery, such as ARM-based CPU power supplies. The device operates with excellent load transient response and is housed in a compact DFN2x2-8L package, making it ideal for space-constrained designs.
