SiC401A, SiC401BCD 15 A microBUCK® SiC401A/B Integrated Buck Regulator with Programmable LDO

PublishTime：2021-06-16

●DESCRIPTION: The Vishay Siliconix SiC401A/B an advanced stand-alone synchronous buck regulator featuring integrated power MOSFETs, bootstrap switch, and a programmable LDO in a space-saving PowerPAK® MLP32-55G pin package. The SiC401A/B is capable of operating with all ceramic solutions 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.
