General Description

The EC3282A is a monolithic synchronous buck regulator.

The device integrates two 130mΩ MOSFETs, and provides 2A of continuous load current over a wide input voltage of 4.75V to 23V. Current mode control provides fast transient response and cycle-by-cycle current limit.

An adjustable soft-start prevents inrush current at turn-on, and in shutdown mode the supply current drops to 1µA.

This device, available in an SOP-8 package provides a very compact solution with minimal external components.

Features

● 2A Output Current

● Up to 93% Efficiency
● Programmable Soft-Start
● Stable with Low ESR Ceramic Output Capacitors
● Fixed 340KHz Frequency
● Cycle-by-Cycle Over Current Protection
● Input Under Voltage Lockout

Applications

● Distributed Power Systems
● Networking Systems
● FPGA, DSP, ASIC Power Supplies
● Green Electronics/ Appliances
● Notebook Computers
