IT7832
5V/2A High Efficiency Step-Down DC/DC Converter
Description
The IT7832 is a low-input voltage and
high-output current synchronous-buck PWM
converter and integrates with all required active
components. Its’ operating input voltage ranges
from 2.7V to 6V and output voltage ranges from
VIN down to 0.8V. The switching frequency is
adjustable ranging from 300kHz to 1.4MHz.
High performance and externally compensation
voltage error amplifier provides design
flexibility and high performance under
transient. In addition,it provides internal
soft-start to reduce inrush-current, current-limit
and thermal shutdown, preventing IC from
being damaged. If the EN pin is floating, it will
be pulled high by the internal circuit.
