AOZ3015PI
EZBuck™ 3 A Synchronous Buck Regulator
General Description
The AOZ3015PI is a high efficiency, easy to use, 3 A
synchronous buck regulator. The AOZ3015PI works from
4.5 V to 18 V input voltage range, and provides up to 3 A
of continuous output current with an output voltage
adjustable down to 0.8 V.
The AOZ3015PI comes in an exposed pad SO-8
package and is rated over a -40 °C to +85 °C operating
ambient temperature range.
Features
4.5 V to 18 V operating input voltage range
Synchronous Buck: 85 mΩ internal high-side switch
and 50 mΩ internal low-side switch (at 12 V)
PEM (pulse energy mode) enables >85% efficiency
with IOUT = 10 mA (VIN = 12 V, VOUT = 5 V)
350 µA supply current under typical application
Up to 95 % efficiency
Internal soft-start
Output voltage adjustable to 0.8 V
3 A continuous output current
500 kHz PWM operation
Cycle-by-cycle current limit
Pre-bias start-up
Short-circuit protection
Thermal shutdown
Exposed pad SO-8 package
