USER GUIDE FOR IR3898 EVALUATION BOARD
1.2Vout
DESCRIPTION
The IR3898 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 IR3898 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
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 IR3898 evaluation board.
The guide describes operation and use of the
evaluation board itself. Detailed application
information for IR3898 is available in the
IR3898 data sheet.
frequency synchronization with smooth
clocking, internal LDO and pre-bias start-
up.
