QFN Package:
protects against over-current and overvoltage conditions by
- Compliant to JEDEC PUB95 MO-220
inhibiting PWM operation. Additional built-in overvoltage

protection triggers an external SCR to crowbar the input
- Near Chip Scale Package footprint, which improves
supply. The HIP6004D monitors the current by using the
PCB efficiency and has a thinner profile

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.
