DESCRIPTION
AIC2933B is a wide input voltage, high efficiency
step-down DC/DC converter that operates in
force PWM mode with adjustable switching frequency.
AIC2933B provides up to 3A output current.
Switching frequency can be set by external
resistor. AIC2933B internal Integrate 80m high
side and 60m low side power MOSFET, which
allows a high efficiency over the wider range of
the load. Advanced production features include
input UVLO, thermal shutdown, soft start and input
and output OVP.
The AIC2933B requires a minimum number of
readily available standard external components
and is available in an 8-pin SOP-8 Exposed Pad.
