AO4844 Datasheet | Alpha & Omega Semiconductors

Description The AO4844 uses advanced trench technology to provide excellent RDS(ON) and low gate charge. The two MOSFETs make a pact and efficient switch and synchronous rectifier bination for use in buck converters. AO4844 is Pb-free (meets ROHS & Sony 259 specifications). AO4844L is a Green Product ordering option. AO4844 and AO4844L are electrically identical. Features VDS (V) = 30V ID = 6.9A (VGS = 10V) RDS(ON) < 28mΩ (VGS = 10V) RDS(ON) < 42mΩ (VGS = 4.5V) D1 S2 G2 S1 G1 1 2 3 4 8 7 6 5 D2 D2 D1 D1 G1 G2 S1 D2 SOIC-8 ..
