ZCC2007 5V/7A高效率同步Boost变换器
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

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.

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.
