SIC417
DESCRIPTION
The Vishay Siliconix Si C417 is an advanced stand-alone synchronous buck regulator featuring integrated power MOSFETs, bootstrap diode, and a programmable LDO in a space-saving MLPQ 5 x 5
- 32 pin package. The Si C417 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 programmable 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 Si C417 also provides an enable input and a power good output.
