microBUCK® 集成降压调节器,带可编程 LDO,Vishay SemiconductorVishay microBUCK® SiC40xA/B 高级独立同步降压调节器集成功率 MOSFET、引导程序开关和可编程低压降 LDO 调节器。 峰值效率为 95%。### 开关电压调节器,Vishay Semiconductor
The is an advanced standalone Synchronous Buck Regulator with programmable LDO featuring integrated power MOSFETs, bootstrap switch. The SiC402A is capable of operating with all ceramic solutions and switching frequencies up to 1MHz. 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 5V for the gate drive circuits or it may be bypassed with an external 5V 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 SiC402A also provides an enable input and a power good output.
