Description

The AOZ1905 EZBoost is a high-performance, currentmode, constant frequency step-up regulator with internal MOSFET. 600kHz/1.2MHz switching frequency allows the use of low-profile inductor and capacitors. The current-mode control ensures easy loop compensation and fast transient response. The AOZ1905 works from a 2.7V to 5.5V input voltage range and generates an output voltage as high as 24V. Other features include input under-voltage lockout, cycle-by-cycle current limit, thermal shutdown and soft-start.

The AOZ1905 is available in a tiny 3mm x 3mm 10-pin DFN package and MSOP8 package and is rated over a -40 to +85 operating temperature range.
