SiC402BCD

www.vishay.com SiC402A, SiC402BCD Vishay Siliconix 10 A microBUCK® SiC402A/B Integrated Buck Regulator with Programmable LDO DESCRIPTION The Vishay Siliconix SiC402A/B an advanced stand-alone synchronous buck regulator featuring integrated power MOSFETs, bootstrap switch, and a programmable LDO in a space-saving PowerPAK MLP55-32L pin packages. The SiC402A/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 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 Si...
