EVALUATION KIT AVAILABLE
5A, 2.4V to 5.5V Input,
High-Efficiency Power Module
General Description
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. The device supports 0.75V
to 3.6V programmable output voltage. The high level of
integration significantly reduces design complexity, manu-
facturing 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 con-
stant 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 cur-
rent 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 x 6.5mm x 2.8mm SIP
package and can operate over the -40°C to +85°C
industrial temperature range.
