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.
he ZCC2410 is a high efficiency, high power
density, wide input range, current mode boost
converter. This converter integrates a 10mΩ,
24V power switch and a synchronous gate
driver for high converter efficiency. It provides
programmable switch peak current limit with an
external resistor. The switching frequency in the
PWM mode is adjustable ranging from 100 kHz
to 1 MHz by an external resistor. An external
compensation pin gives the user flexibility in
setting loop dynamics and obtaining the optimal
transient performance at all conditions.
