Analog Devices / Maxim Integrated Himalaya uSLIC™ MAXM1546x Step-Down Power Modules

Analog Devices Himalaya uSLIC™ MAXM1546x Compact Step-Down Power Modules feature an integrated circuit and inductor that operate over a wide input-voltage range. The modules operate from a 4.5V to 42V input and deliver up to 300mA output current over a programmable output voltage from 0.9V to 5V. These easy-to-use step-down power modules significantly reduce design complexity, manufacturing risks, and offer a true plug-and-play power-supply solution.

The devices employ 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 MAXM1546x offers an internal soft-start to reduce input inrush current. The modules are available in a low profile, compact 10-pin, 2.6×3×1.5mm, uSLIC™ package. The devices operate over a wide temperature range from -40°C to +125°C.
