ZCC2003 0.8V Start-up VIN&5V/2.5A High Efficiency Synchronous Boost Converter

PublishTime：2021-12-28

The ZCC2003 is a high efficiency, high power density, current mode, fully integrated boost converter with output disconnect, which can start up from an input voltage as low as 0.8V and convert up to 5.5V output voltage. During shutdown, it can disconnect the output from input.
This converter integrates two 100mΩ power switches for high converter efficiency and can deliver >1A output current at 5V output with 2.5V input supply. When the output is shorted, the ZCC2003 enters hiccup protection mode and recover automatically when the output short is removed.
The ZCC2003 also includes input under-voltage lockout, output over-voltage protection, cycle-by-cycle over-current protection, short circuit protection and thermal shutdown to prevent damage in the event of output overload.
The ZCC2003 is available in a small 6-pin SOT23 package.
