The HT8903 is a non-synchronous boost converter integrated with a 60mΩ power switch to provide a high efficiency and small size solution in portable systems.
The HT8903 has an input voltage range from 2.5 V to 9V to support applications with single cell and two cell Lithium batteries. The device has 7A switch current capability and can provide an output voltage up to 9V.
A function of adjustable Current limitation is available to protect HT8903 from over current during operation, and to prevent the battery from being over-pulled caused by an overload.
The HT8903 is available in SOP8L-PP, with very limited external components, so that it provides space-saving PCB for various applications.
The HT8903 provides 10V output overvoltage protection, and thermal shutdown protection.
