Maxim introduces the MAX8552 single-phase MOSFET driver IC optimized to complement the MAX8524/MAX8525 high-performance CPU core-supply controllers. Featuring an input range of 6 V to 24 V, the MAX8552 drives the upper and lower MOSFETs in synchronous-buck, DC-DC converters. With 0.1 microamps (typical) quiescent current over the entire temperature range, the MAX8552 drives 3000 pF capacitive loads with 12 ns propagation delay, with rise and fall times of 11 ns (typical). This enables operation up to 2 MHz per phase with the TDFN package and up to 1.2 MHz per phase with the microMAX package.
