WPMDB1400362Q / 171040302

MagI³C Power Module

VDRM – Variable Step Down Regulator Module

2.95 – 6V / 4A / 0.8 – 3.6V Output

DESCRIPTION

FEATURES

Peak efficiency up to 96%

The Magi3C 171020302, 171040302 and 171060302

Power Module family provide a fully integrated DC-DC

power supply including the switching regulator, regulation

loop, power mosfets and shielded inductor in one

package. This modules require as few as 3 external

components



Current capability up to 4A

Output voltage range: 0.8 to 3.6V

Current Mode control

Synchronuos operation

1% reference accuracy over temperature

Adjustable switching frequency (0.5 to 2 MHz)

Continuous output power: 14.4W

No derating within the operating temperature range

Integrated shielded inductor

The 171040302 offers high efficiency and delivers up to

4A of output current. It operates from 2.95 to 6V input

voltage and is designed for fast transient response.

Under-voltage lockout protection

Programmable soft-start and voltage tracking

Frequency synchronization to external clock

Thermal shutdown

It is available in a standard industrial high power density

QFN package (11mm x 9mm x 2.8mm) with very good

thermal performance.

Operating ambient temperature up to 85°C

Inrush current protection

This module has an on-board protection circuitry to guard

against thermal overstress and electrical damage

featuring thermal shut-down, over-current, short-circuit,

over-voltage and under-voltage protections.

Adjustable soft start and sequencing

Cycle by cycle short circuit protection

Under-voltage and over-voltage Power Good

Pin compatible with WE171040302 & WE171060302

Complies with EN55022 class B radiated emissions

standard
