USER GUIDE FOR IR3899 EVALUATION BOARD

1.2Vout

DESCRIPTION

The

IR3899

is

a

synchronous

buck

converter,

providing

a

compact,

high

performance and flexible solution in a small

4mm X 5 mm Power QFN package.

Key features offered by the IR3899 include

internal Digital Soft Start/Soft Stop, precision

0.5Vreference

voltage,

Power

Good

,

thermal protection, programmable switching

frequency, Enable input, input under-voltage

lockout for proper start-up, enhanced line/

load regulation with feed forward, external

frequency

synchronization

with

smooth

clocking, internal LDO

and pre-bias start-

up.

Output over-current protection function is

implemented by sensing the voltage developed

across the on-resistance of the synchronous

Mosfet for optimum cost and performance and

the current limit is thermally compensated.

This user guide contains the schematic and bill

of materials for the IR3899 evaluation board.

The guide describes operation and use of the

evaluation board itself. Detailed

application

information for IR3899 is available in the

IR3899 data sheet.
