Supporting voltages up to 28 V, the AAT4910 half-bridge, dual MOSFET driver from AnalogicTech is billed as featuring the industry’s lowest impedance in its class for multiphase DC-DC converters. With a 3-? drive resistance, the driver is powered from a 5-V rail. When driven low, the enable input turns off the driver and reduces operating current to less than 1 µA. The driver is qualified across the -40º C to +85º C temperature range. From $0.48 in 1K quantities.
