5A, 2.4V to 5.5V Input,

High-Efficiency Power Module

General Description

Beneﬁts and Features

●ꢀ CompleteꢀSwitch-ModeꢀPowerꢀSupplyꢀinꢀOneꢀ

The MAX17515 is

fixed-frequency, step-down

power module in

thermally efficient system-

Package

in-package (SIP) package that operates from

●ꢀ 2.4Vꢀtoꢀ5.5VꢀInputꢀVoltageꢀRange

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.

• Thermal-Fault Protection

• PeakꢀCurrentꢀLimit

●ꢀ EnableꢀInputꢀ

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.

package and can operate over the -40°C to +85°C

industrial temperature range.
