HT7181
The HT7181 is a high power asynchronous boost converter with an integrated 20mΩ power switch tube to provide an efficient, small size solution for portable systems.
With a wide input voltage range of 2.7V to 16V, the HT7181 supports applications using single or two lithium batteries, or 12V lead-acid batteries. The device has a 14A switching current capability and is capable of delivering output voltages up to 16.8V.
The HT7181 also supports programmable soft start, as well as adjustable switching peak current limits. The HT7181 also supports two different tr/tf to accommodate different EMI and efficiency needs.
In addition, the device provides 18V output overvoltage protection and thermal shutdown protection.
