FR9888C

23V, 3.5A, 340KHz Synchronous Step-Down

DC/DC Converter

Description

Features

The FR9888C is a synchronous step-down DC/DC

converter that provides wide 4.5V to 23V input

voltage range and 3.5A continuous load current

capability.

 High Efficiency up to 96%

 Low Rds(on) Integrated Power MOSFET

(110mΩ/80mΩ)

 Wide Input Voltage Range: 4.5V to 23V

 Adjustable Output Voltage Range: 0.925V to 20V

 3.5A Output Current

The

FR9888C

fault

protection

includes

cycle-by-cycle current limit, input UVLO, output over

voltage protection and thermal shutdown. Besides,

adjustable soft-start function prevents inrush current

at turn-on. This device uses current mode control

scheme which provides fast transient response.

In shutdown mode, the supply current is less than

1μA.

 Fixed 340kHz Switching Frequency

 Current Mode Operation

 External Compensation Function

 Adjustable Soft-Start

 Cycle-by-Cycle Current Limit

 Input Under Voltage Lockout

 Over-Temperature Protection with Auto Recovery

 <1μA Shutdown Current

The FR9888C is available in SOP-8 exposed pad

package, provides a very compact system solution

and good thermal conductance.

 SOP-8 Exposed Pad Package

Applications

 Set-Top-Box (STB)

 LCD Displays, TV

 Distributed Power System

 XDSL Modem
