USER GUIDE FOR IR3897 EVALUATION BOARD

1.2Vout

DESCRIPTION

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.

The IR3897 is

converter, providing

performance and flexible solution in a small

4mm X 5 mm Power QFN package.

synchronous buck

compact, high

Key features offered by the IR3897 include

internal Digital Soft Start/Soft Stop, precision

This user guide contains the schematic and bill

of materials for the IR3897 evaluation board.

The guide describes operation and use of the

evaluation board itself. Detailed application

information for IR3897 is available in the

IR3897 data sheet.

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.
