描述
MAX15158Z is a high-voltage multiphase boost controller designed to support up to two MOSFET drivers and four external MOSFETs in single-phase or dual-phase boost/inverting-buck-boost configurations. Two devices can be stacked up for quad-phase operation. The output voltage of MAX15158Z can be dynamically set through the 1V to 2.2V reference input (REFIN) for modular design support.
The switching frequency is controlled either through an external resistor setting the internal oscillator or by synchronizing the regulator to an external clock. The device is designed to support 120kHz to 1MHz switching frequencies. The controller has a dedicated enable/input undervoltage-lockout (EN/UVLO) pin to configure for flexible power sequencing.
MAX15158Z has a dedicated RAMP pin to adjust internal slope compensation. The device features adjustable overcurrent protection. The device incorporates current sense amplifiers to accurately measure the current of each phase across external sense resistors to implement accurate phase current sharing. The controller is also protected against output overvoltage, input undervoltage and thermal shutdown.
The device is available in 5mm x 5mm, 32-pin TQFN package and supports -40°C to 125°C junction temperature range.
