HT7182 -21V, 14A高效升压转换器
The HT7182 is a high-power density, asynchronous boost
converter with a 20mΩ power switch to provide a high
efficiency and small size solution in portable systems. The
HT7182 has wide input voltage range from 2.7 V to 25 V to
support applications with single cell, two cell Lithium
batteries and 12V lead-acid batteries. The device has 14A
switch current capability and can provide an output voltage
up to 26.8V.
The HT7182 also implements a programmable soft-start
function and an adjustable switching peak current limit
function. HT7182 integrates two modes with different tr/tf to
balance different requirements of EMI and efficiency.
In addition, the device provides thermal shutdown
protection.
