Analog Devices / Maxim Integrated Himalaya uSLIC™ MAXM1506x Step-Down Power Modules

Analog Devices Himalaya uSLIC™ MAXM1506x Step-Down Power Modules are high-efficient, synchronous step-down DC-DC modules with integrated circuits and inductors that operate over a wide input voltage range. The modules operate from a 4.5V to 60V input and deliver up to 300mA output current over a programmable output voltage from 0.9V to 5V. The modules are easy-to-use, step-down power modules that significantly reduce design complexity and manufacturing risks and offer a true plug-and-play power-supply solution, reducing time-to-market. The devices employ a peak-current-mode control architecture through the MODE pin that can be used to operate the devices in pulse-width modulation (PWM) or pulse frequency modulation (PFM) control schemes. The Analog Devices Himalaya uSLIC™ MAXM1506x offers an internal soft-start to reduce input inrush current.
