General Description
The AOZ1915 is a high-performance, current-mode,
constant frequency boost regulator with internal
MOSFET and internal Schottky diode. The 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 AOZ1915 works from a 2.7V to 5.5V input
voltage range and generates an output voltage as high
as 22V. Other features include input under-voltage
lockout, cycle-by-cycle current limit, thermal shutdown
and soft-start.
The AOZ1915 is available in a tiny 4mm x 3mm 12-pin
DFN package and is rated over a -40°C to +85°C
