5V7A同步升压转换器-ZCC2007

5V7A同步升压转换器-ZCC2007

Description 

The ZCC2007 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 1.8V and convert up to 5.5V output voltage. During shutdown, it can disconnect the output from input. 

The ZCC2007 also includes input under-voltage Applications lockout, output over-voltage protection, cycleby-cycle over-current protection, short circuit protection and thermal shutdown to prevent damage in the event of output overload. The ZCC2007 is available in a low profile 11-pin 2mmx2mm FCQFN package. 

Features :

  Input Voltage Range: 1.8V to 5.5V Output Voltage Range: 2.5V to 5.5V 7-A Peak Switching Current Limit Two 20-mΩ(LS)/20-mΩ(HS) MOSFETs 40uA Quiescent Current Internal Compensation and Soft-start True Load Disconnect from Input Low Shutdown Current < 1µA This converter integrates two 7A/20mΩ power switches for high converter efficiency and can deliver up to 2.5-A output current at 5V output with 2.5V input supply. When the output is shorted, the ZCC2007 enters hiccup protection mode and recover automatically when the output short is removed. Output Overvoltage Protection OVP, OCP, SCP and OTP Protection High Efficiency over Whole Load Range Small 2x2mm QFN 11-Pin Package
