SiC414, SiC424  
Vishay Siliconix  
6 A, microBUCK® SiC414, SiC424  
Integrated Buck Regulator with 5 V LDO  
DESCRIPTION  
FEATURES  
High efficiency > 95 %  
The Vishay Siliconix SiC414 and SiC424 are an advanced  
stand-alone synchronous buck regulator featuring integrated  
power MOSFETs, bootstrap switch, and an internal 5 VLDO  
in a space-saving PowerPAK MLP44-28L package.  
6 A continuous output current capability  
Integrated bootstrap switch  
Integrated 5 V/200 mA LDO with bypass logic  
Temperature compensated current limit  
The SiC414 and SiC424 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 Siliconix SiC414 and SiC424 also  
provides an enable input and a power good output.  
Pseudo fixed-frequency adaptive on-time  
control  
All ceramic solution enabled  
Programmable input UVLO threshold  
Independent enable pin for switcher and LDO  
Selectable ultrasonic power-save mode (SiC414)  
Selectable power-save mode (SiC424)  
Internal soft-start and soft-shutdown  
1 % internal reference voltage  
Power good output and over voltage protection
