Summary of MAXIM INTEGRATED MAXM17625/MAXM17626 USLIC™ STEP-DOWN POWER MODULES
Maxim Integrated MAXM17625 and MAXM17626 uSLIC step-down power modules are compact, high-frequency synchronous DC-DC regulators with integrated MOSFETs, inductors, and compensation. They accept 2.7V–5.5V input, provide adjustable outputs from 0.8V–3.3V (ranges split between the two parts), deliver up to 600mA, and offer selectable PWM or PFM light-load modes (MAXM17625: 2MHz; MAXM17626: 4MHz). Features include ±1% feedback accuracy, internal compensation, soft-start, power-good output, low shutdown current, 100% duty capability, protection and rugged environmental qualifications in a 10-pin uSLIC package.

Maxim Integrated MAXM17625/MAXM17626 uSLIC™ Step-Down Power Modules are high-frequency Himalaya synchronous step-down DC-DC modules with integrated MOSFETs, compensation components, and inductors. The MAXM17625 and MAXM17626 support up to 600mA load current and allow the use of small, low-cost input and output capacitors. The Modules operate over a wide 2.7V to 5.5V input voltage range. The output voltage is adjustable from 0.8V to 3.3V.
The Maxim MAXM17625 and MAXM17626 Power Modules utilize a peak-current-mode control architecture under steady-state operation. The 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 runs 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 housed in a low profile, compact 10-pin, 2.6mm x 2.1mm x 1.3mm, uSLIC package.
