Fairchild Adds N-Channel & Schottky Diode Combination for Smartphone Backlighting Applications

Fairchild Semiconductor introduced the FDZ3N513ZT – an N-Channel and Schottky diode combination in a small 1 x 1mm footprint. The FDZ3N513ZT is an integral element of the boost converter that drives white LEDs in a series string to illuminate the smartphone display (and keys, if a keypad is present).

This solution features low switching losses due to the precise optimization of dynamic characteristics, resulting in high conversion efficiency and longer battery life in cell phone applications.

The FDZ3N513ZT incorporates a 30V integrated N-Channel MOSFET and Schottky diode, featuring exceptionally low typical input capacitance (45pF) and total gate charge (1nC) to improve efficiency in boost converter designs.

The FDZ3N513ZT is housed in a 1 x 1 mm WL-CSP package and saves 60% of board space when compared to devices in 1.6 x 1.6mm packaging.

The FDZ3N513ZT is priced at US $0.75 in 1,000 quantity pieces with a delivery of 12 weeks ARO.
