CST2116 Overview:
CST2116 is a synchronous boost DC-DC with low standby power consumption and high efficiency, with a standby current of only 15uA.
CST2116 adopts a fixed conduction time PFM control method, which automatically reduces the switching frequency to maintain high conversion efficiency under light load.
CST2116 only requires 3 components on the periphery to convert the low input battery voltage to the required operating voltage.
CST2116 adopts patented control technology, which has the characteristics of low standby power consumption and light load efficiency. CST2116 can achieve an input current of only 15uA while maintaining output voltage boost and voltage stabilization, making it particularly suitable for applications with high standby time requirements.
CST2116 adopts SOT23-3 and SOT23-5 packaging.
