1.6A 23V Synchronous Rectified Step-Down Converte TD1482
General Description
Features
The TD1482 is a monolithic synchronous buck • 1.6A Output Current
regulator. The device integrates two 130mΩ • Wide 4.75V to 23V Operating Input Range
MOSFETs, and provides 1.6A of continuous load • Integrated 130mΩ Power MOSFET Switches
current over a wide input voltage of 4.75V to 23V. • Output Adjustable from 0.923V to 20V
Current mode control provides fast transient • Up to 93% Efficiency
response 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
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
