23V, 2A, 600KHz Asynchronous Step-Down
DC/DC Converter
Description
Features
The FR97063A is a monolithic step-down switch
mode converter with a built-in power MOSFET. It
achieves 2A output current over a wide input supply
range with excellent load and line regulation.
Current mode operation provides fast transient
● 2A Output Current
● 180mΩ Internal Power MOSFET Switch
● Stable with Low ESR Output Ceramic Capacitors
● Up to 92% Efficiency
● Fixed 600KHz Frequency
response and eases loop stabilization.
Fault
● Current Mode Operation
condition protection includes cycle-by-cycle current
limit and thermal shutdown.
● Thermal Shutdown
● Cycle-by-Cycle Over Current Protection
● Wide 4.5V to 23V Operating Input Range
● Output Adjustable from 0.805V to 15V
● 10μA Shutdown Current
● Available in SOP-8 and MSOP-10 (Exposed Pad)
Packages
The FR97063A is available in SOP-8 and MSOP-10
(exposed pad) packages, which provides a very
compact system solution and good thermal
conductance.
Applications
● Distributed Power System
