SIC401DB: 0.6 ~ 5.5V @ 15A, 3 ~ 17V in
1 января 2018
The Vishay Siliconix SiC401A/B, SiC402A/B and SiC403A/B are advanced stand-alone synchronous buck regulators, featuring integrated power MOSFETs, bootstrap switch, and a programmable LDO in a space-saving PowerPAK MLP55-32L pin packages.
The SiC401A/B, SiC402A/B and SiC403A/B are capable of operating with all ceramic solutions and switching frequencies up to 1 MHz. The programmable frequency, synchronous operation and selectable power-save feature 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. Both the SiC401A/B, SiC402A/B and SiC403A/B provides an enable input and a power good output.
