Integrated power switches comes in wafer level chip scale packaging

SILEGO GFET3 Integrated Power Switch (IPS) portfolio addresses extremely pcb-space-constrained, high-performance applications in tablet PC, smartphones and fitness band markets. The three performance-driven WLCSP products cover high-side power control applications from 1A to 4A. The 0.64 mm2 (0.8mm x 0.8 mm) SLG59M1730C (33mOhm/1 A) and the SLG59M1736C (33 mOhm/2.2 A) are low-leakage, self-powered pFET IPSs that can operate from 2.5 V to 5.5 V supply voltages and draw very little supply current. Both products offer low-threshold ON/OFF control, fast output voltage discharge and a novel, controlled input current profile on startup. www.silego.com
