New Product Introduction

Maxim Integrated – Himalaya µSLIC Power Modules

Tiny sizes, widest voltage range for Industry 4.0: Meet the new µSLIC power modules: MAXM17623 & MAXM17624

Maxim Integrated Himalaya uSLIC Power Modules

Himalaya uSLIC™ power modules offer the smallest packages available, while accepting a wide input voltage from 4.0V to 60V. Himalaya uSLIC power modules leverage advanced packaging technology to shrink the power supply solution size by 2.25 times, resulting in micro-sized system-level IC (uSLIC) devices. This is achieved by integrating a synchronous wide-input Himalaya buck converter—which includes built-in FETs, compensation, and additional functions—with an inductor.

The combination of these components results in ultra-small power modules that can be used in highly space-constrained systems while complying with the JESD22-B103/B104/B111 mechanical standard. In addition, compliance with the CISPR 22 electromagnetic interference (EMI) standard helps to improve the first-time success rate for EMI certification of your end products.

Evaluation kits are available for: MAXM17903, MAXM17552, MAXM17900 and MAXM15064.

MAXM17623 - 2.9V to 5.5V, 1A Himalaya uSLIC Step-Down Power Modules

High-Efficiency Synchronous Buck Regulator Offers Balance of High Performance, Wide Temperature Range, and Small Size

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.
