1-mm2 boost switch saves 60% board space

The FDZ3N513ZT is an n-channel MOSFET and Schottky diode combined in a 1 x 1-mm footprint WL-CSP package and saves 60% of board space compared to devices in 1.6-mm2 packaging. It is an integral element of the boost converter that drives white LEDs in a series string to illuminate the smart-phone display and keys.

The boost switch 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. It incorporates a 30-V n-channel MOSFET, features a 45-pF input capacitance and 1-nC total gate charge. Datasheet: www.fairchildsemi.com/ds/FD/FDZ3N513ZT.pdf.
