资料介绍

ZCC2007是一款高效率、高功率密度、电流模式的带输出隔离开关的全集成升压变换器，它可以从低至1.8V的输入电压启动，最高可转换至5.5V的输出电压。在关机期间，它可以将输出与输入断开。

该转换器集成了两个7A/20mΩ电源开关，可在5V输出时提供大于2.5A的输出电流2.5V输入电源。当输出短路时，ZCC2007进入打嗝保护模式输出短路消除后自动恢复。

ZCC2007还包括输入欠压闭锁、输出过电压保护、循环过电流保护、短路保护和热关机，以防止输出过载时损坏。

特征:

•输入电压范围：1.8V至5.5V

•输出电压范围：2.5V至5.5V

•7-A峰值开关电流限值

•两个20-mΩ（LS）/20-mΩ（HS）mosfet

•40uA静态电流

•内部补偿和软启动

•真负载与输入断开

•低关机电流<1微安

•OVP、OCP、SCP和OTP保护

•在整个负载范围内高效

应用：

平板

USB电源

电池供电产品

备用电池组

ZCC2007  
5V/7A High Efficiency Synchronous Boost Converter  
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.

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  
Applications  
The ZCC2007 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  
ZCC2007 is available in a low profile 11-pin  
2mmx2mm FCQFN package.

Storage Temp..........................-65°C to +150°C  
Notes:  
1) Exceeding these ratings may damage the device.  
2) The maximum allowable power dissipation is a function of the  
maximum junction temperature TJ (MAX), the junction-to-  
ambient thermal resistance θJA, and the ambient temperature  
TA. The maximum allowable continuous power dissipation at  
any ambient temperature is calculated by PD (MAX) = (TJ  
(MAX)-TA)/θJA. Exceeding the maximum allowable power  
dissipation will cause excessive die temperature, and the  
regulator will go into thermal shutdown. Internal thermal  
shutdown circuitry protects the device from permanent  
damage.
