ISL8025A
ISL8025A is Compact Synchronous Buck Regulators manufactured by Renesas.
- Part of the ISL8025 comparator family.
- Part of the ISL8025 comparator family.
features include internal fixed or adjustable soft-start and internal/external pensation.
The ISL8025, ISL8025A are offered in a space saving 16 Ld 3x3 Pb-free QFN package with an exposed pad for improved thermal performance and 1mm maximum height. The plete converter occupies less than 0.22 in2 area.
