MAX15159 Multiphase Boost/Flyback Controllers

Analog Devices Inc. MAX15159 Multiphase Boost/Flyback Controllers are high-voltage devices with enhanced low-side MOSFET gate driver capability supporting 120kHz to 1MHz switching frequencies. MAX15159 supports single-phase or dual-phase boost/flyback configurations. Two devices can be stacked up for triple-phase or quad-phase operation. The output voltage can be dynamically set through a 1.5V to 2.2V reference input (REFIN) for modular design support. The switching frequency is controlled by an external resistor setting the internal oscillator or by synchronizing the regulator to an external clock.
