AOZ3046PI Datasheet | Alpha & Omega Semiconductors

EZBuck™ 4 A Synchronous Buck Regulator General Description The AOZ3046PI is a high efficiency, simple to use, 4 A synchronous buck regulator. The AOZ3046PI operates from a 7.5 V to 18 V input voltage range, and provides up to 4 A of continuous output current with an output voltage adjustable down to 0.8 V. The AOZ3046PI es in an exposed pad SO-8 package and is rated over a -40 °C to +85 °C operating ambient temperature range. Features - 7.5 V to 18 V operating input voltage range - 350 µA quiescent current typical applications - 60 mΩ internal high-side switch and 30 mΩ internal low-side switch (at 12 V) - PEM (pulse energy mode) enables 82 % plus efficiency with IOUT = 10 m A (VIN = 12 V, VOUT = 5 V) - Up to 95 % efficiency - Internal soft start - Output voltage adjustable to 0.8 V - 4 A continuous output current - 500 k Hz PWM operation - Cycle-by-cycle current limit - Pre-bias start-up - Short-circuit protection - Thermal shutdown -...
