FR9886C

21V, 2A/2.5A, 340KHz Synchronous Step-Down

DC/DC Converter

Description

Features

The FR9886C is a synchronous step-down DC/DC

converter that provides wide 4.5V to 21V input

voltage range. There are two packages (SOP-8 &

SOP-8(EP)) to support 2A/2.5A continuous output

current.

● High Efficiency Synchronous Buck Converter with

Low I_SD(<1μA)

● Low Rds(on) Integrated Power MOSFET

● Wide Input Voltage Range: 4.5V to 21V

● Adjustable Output Voltage from 0.925V to 17.85V

● 2A Output Current (Package: SOP-8)

● 2.5A Output Current (Package: SOP-8(EP))

● Fixed 340KHz Switching Frequency

● Current Mode Operation

● Adjustable Soft-Start

● Cycle-by-Cycle Current Limit

● Input Under Voltage Lockout

The

FR9886C

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.

● Over-Temperature Protection with Auto Recovery

● SOP-8 and SOP-8 Exposed Pad Packages

The FR9886C is available in SOP-8 and SOP-8

exposed pad packages. It is RoHS compliant and

100% lead (Pb) free.

Applications

● Set-Top-Box

● DVD,LCD Display

● OLPC, Netbook

● Distributed Power System

● Datacom, XDSL
