• 650kHz/1.3MHz switching frequency

• Integrated sequencing

The asynchronous buck converter features an integrated

2.5A FET. It also operates from the 650kHz or 1.3MHz

internal clock and features separate enable and soft-start

control.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100%

matte tin plate termination finish, which are RoHS compliant and

compatible with both SnPb and Pb-free soldering operations. Intersil

Pb-free products are MSL classified at Pb-free peak reflow

temperatures that meet or exceed the Pb-free requirements of

IPC/JEDEC J STD-020.
