HT7180-12.8V, 10A高效升压转换器
The HT7180 is a high-power density, asynchronous boost
converter with a 22mΩ power switch to provide a high
efficiency and small size solution in portable systems. The
HT7180 has wide input voltage range from 2.7 V to 12 V to
support applications with single cell and two cell Lithium
batteries. The device has 10A switch current capability and
can provide an output voltage up to 12.8V.
The HT7180 also implements a programmable soft-start
function and an adjustable switching peak current limit
function. HT7180 integrates two modes with different tr/tf to
balance different requirements of EMI and efficiency.
In addition, the device provides 13V output overvoltage
protection, and thermal shutdown protection.
