IHLP4040DZER6R8M01

Product Summary

The ihlp4040dzer6r8m01 is a 15 A microBUCK SiC401A/B Integrated Buck Regulator with Programmable LDO. The ihlp4040dzer6r8m01 is capable of operating with all ceramic solution and switching frequencies up to 1 MHz. The programmable frequency, synchronous operation and selectable power-save allow operation at high efficiency across the full range of load current. The internal LDO may be used to supply 5 V for the gate drive circuits or it may be bypassed with an external 5 V for optimum efficiency and used to drive external n-channel MOSFETs or other loads. Additional features include cycle-by-cycle current limit, voltage soft-start, under-voltage protection, programmable over-current protection, soft shutdown and selectable power-save. The Vishay Siliconix SiC401A/B also provides an enable input and a power good output. It is ideal for: (1)Notebook, desktop and server computers; (2)Digital HDTV and digital consumer applications; (3)Networking and telecommunication equipment; (4)Printers, DSL, and STB applications; (5)Embedded applications; (6)Point of load power supplies.
