www.vishay.com SiC403A, SiC403BCD Vishay Siliconix 6 A microBUCK® SiC403A/B Integrated Buck Regulator with Programmable LDO DESCRIPTION The Vishay Siliconix SiC403A/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 packages. The SiC403A/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.
