描述

The Himalaya series of voltage regulator ICs, power modules, and chargers enable cooler, smaller, and simpler power supply solutions. MAXM17625 and MAXM17626 are high-frequency Himalaya synchronous step-down DC-DC uSLICTM modules with integrated MOSFETs, compensation components, and inductors, that operate over a wide 2.7V to 5.5V input voltage range. MAXM17625 and MAXM17626 support up to 600mA load current and allow use of small, low-cost input and output capacitors. The output voltage can be adjusted from 0.8V to 3.3V. The modules significantly reduce design complexity, manufacturing risks, and offer a true plug-and-play power supply solution, reducing time-to-market.

The MAXM17625 and MAXM17626 modules employ peak-current-mode control architecture under steady-state operation. To reduce input inrush current, the devices offer a fixed 1ms soft-start time. Both modules feature selectable PWM or PFM mode of operation at light loads. When PWM mode is selected, MAXM17625 operates at a fixed 2MHz switching frequency and MAXM17626 operates at a fixed 4MHz switching frequency. MAXM17625 offers output voltages from 0.8V to 1.5V and MAXM17626 offers output voltages from 1.5V to 3.3V.

The MAXM17625 and MAXM17626 modules are available in a low profile, compact 10-pin, 2.6mm x 2.1mm x 1.3mm, uSLIC package.
