Analog Devices / Maxim Integrated MAX15158Z High-Voltage Multiphase Boost Controller
Analog Devices MAX15158Z High-Voltage Multiphase Boost Controller is a high-voltage multiphase boost controller. The device supports up to two MOSFET drivers and four external MOSFETs in single- or dual-phase boost/inverting-buck-boost configurations. Two devices can be stacked for quad-phase operation. The MAX15158Z's output voltage can be dynamically set through the 1V to 2.2V reference input (REFIN) for modular design support.Features
