3A 23V Synchronous Rectified Step-Down Converter TD1484
General Description
Features
The TD1484 is a monolithic synchronous buck 3A Output Current
regulator. The device integrates two 90mΩ Wide 4.75V to 23V Operating Input Range
MOSFETs, and provides 3A of continuous load current Integrated 90mΩ Power
MOSFET Switches
over a wide input
voltage of 4.75V to 23V. Current Output Adjustable from 0.923V to 20V
mode control provides fast transient response Up to 93% Efficiency
and cycle-by-cycle current limit.
Programmable Soft-Start
An adjustable soft-start prevents inrush current at turn-on, and in shutdown mode the supply current
Stable with Low ESR Ceramic Output
Capacitors
drops to 1µA.
Fixed 340KHz Frequency
This device, availablein an SOP8-PP package, Cycle-by-Cycle Over Current Protection
provides a very compact solution with minimal external Input Under
Voltage Lockout
components.
Applications
Distributed Power Systems Networking Systems FPGA, DSP, ASIC Power Supplies Green Electronics/ Appliances Notebook Computers
