SiC403 Vishay Siliconix microBUCK® SiC403 6 A, 28 V Integrated Buck Regulator with Programmable LDO DESCRIPTION The Vishay Siliconix SiC403 is an advanced stand-alone synchronous buck regulator featuring integrated power MOSFETs, bootstrap switch, and a programmable LDO in a space-saving MLPQ 5 x 5 - 32 pin package. The SiC403 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.
