概述

说明

The Himalaya series of voltage regulator ICs and power modules enable cooler, smaller, and simpler power-supply solutions. MAXM17623 and MAXM17624 are high-frequency synchronous step down DC-DC converter modules, with integrated MOSFETs, compensation components, and inductors, that operate over 2.9V to 5.5V input voltage range. MAXM17623 and MAXM17624 support up to 1A 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 MAXM17623 and MAXM17624 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, MAXM17623 operates at a fixed 2MHz switching frequency and MAXM17624 operates at a fixed 4MHz switching frequency. MAXM17623 offers output voltages from 0.8V to 1.5V and MAXM17624 offers output voltages from 1.5V to 3.3V.

The MAXM17623 and MAXM17624 modules are available in a low profile, compact 10-pin, 2.6mm x 2.1mm x 1.3mm, uSLIC™ package.
