AOZ2378QI规格书详情
General Description
The AOZ2378QI is a high-efficiency, easy-to-use DC/DC
synchronous buck regulator that operates over a wide 6.5 V
to 24 V voltage range.The device is capable of supplying
25 A of continuous output current with an output voltage
adjustable down to 0.6 V (±1.0).
The AOZ2378QI integrates an internal linear regulator to
generate 5.3 V VCC from input. If input voltage is lower than
5.3 V, the linear regulator operates at low drop output mode,
which allows the VCC voltage is equal to input voltage minus
the drop-output voltage of the internal linear regulator.
A proprietary constant on-time PWM control with input
feed-forward results in ultra-fast transient response while
maintaining relatively constant switching frequency over
the entire input voltage range. A low 80 ns minimum on-time
enables very low output voltages at ultra-high operating
frequencies.
Integrated AC ripple injection enables all-ceramic low ESR
output filter capacitors and smaller PCB footprint with no
external components needed.
Selectable PFM mode optimizes light load efficiency while
forced PWM mode maintains constant frequency for lower
harmonic noise.
The device features multiple protection functions such as
VCC under-voltage lockout, cycle-by-cycle current limit,
output over-voltage protection, short-circuit protection, and
thermal shutdown.
The AOZ2378QI is available in a 5 mm×5 mm QFN-28L
package and is rated over a -40°C to +85°C ambient
temperature range.
