10A Smart Load Switch claims Best-in-Class RDS(ON)-to-Footprint RatioJune 29, 2014 by Jeff Shepard
Alpha and Omega Semiconductor Limited (AOS) today announced the release of the AOZ1334, a single-channel EZPower™ Smart Load Switch. The device features an ultra-low on-resistance of 3.9mΩ (VIN = 1.05V, VBIAS = 5V, TA = 85 degrees C), and delivers up to 10A of continuous current in a thermally enhanced 3mm x 3mm DFN package. The AOZ1334 offers high efficiency in a compact size, and is a suited for a variety of space-constrained applications such as tablets, notebook computers, set-top-boxes, solid-state drives, networking equipment, LCD TVs, and other consumer electronics applications.
The AOZ1334 includes an n-channel MOSFET that can provide 10A of current with a 3.2V to 5.5V bias supply, and operates down to 0.8V. The MOSFET turn-on time is controlled by a low voltage control signal through the ON pin. Additionally, an internal 220Î© load discharge resistor is integrated to allow quick discharging of capacitive output loads.
â€œWith its ultra-low on-resistance and high current capability, the AOZ1334 offers industry-leading performance, making it a great solution for applications that require compact and efficient load switching.â€ said Daniel Chang, Vice President of the Power IC Product Line at AOS. â€œIt simplifies designs by including features such as slew rate control and load discharge, which eliminates input supply glitches and other noise.â€
The AOZ1334 is immediately available in production quantities with a lead-time of 12 weeks. The unit price of 1,000 pieces is $0.66.
