Input, High-Efficiency Power Module


Create a design and simulate using EE-Sim: [MAX17515]
The MAX17515 is a fixed-frequency, step-down power module in a thermally efficient system-in-package (SIP) package that operates from a 2.4V to 5.5V input supply voltage and supports output currents up to 5A. The device includes switch-mode power-supply controller, dual n-channel MOSFET power switches, a fully shielded inductor, as well as compensation components.
Input, High-Efficiency Power Module
The device supports 0.75V to 3.6V programmable output voltage. The high level of integration significantly reduces design complexity, manufacturing risks, and offers a true “plug-and-play” power-supply solution, reducing the time to market.
The device operates at a fixed 1MHz that requires smaller input and output capacitor size. The internal fixed constant gain at the error-amplifier output results in output-voltage positioning with respect to the load current. The fixed internal digital soft-start limits the input inrush current at startup. The device also operates in pulse-skipping mode at light loads to improve the light-load efficiency.
The MAX17515 is available in a thermally enhanced, compact 28-pin, 10mm × 6.5mm x 2.8mm SIP package and can operate over the -40°C to +85°C industrial temperature range.
