MAX20029/MAX20029B/

MAX20029C/MAX20029D

Automotive Quad/Triple Low-Voltage

Step-Down DC-DC Converters

General Description

Beneﬁts and Features

● Quad Step-Down DC-DC Converters with Integrated

The MAX20029/MAX20029B/MAX20029C/MAX20029D

power-management ICs (PMICs) integrate four low-volt-

age, high-efficiency, step-down DC-DC converters. Each

of the four outputs is factory or resistor programmable

between 1V to 4.0V (MAX20029/MAX20029B) or 0.7V

to 3.8V (MAX20029C/MAX20029D). The MAX20029/

MAX20029C has two 0.5A/1A/1.5A channels and two

0.5A/1.5A channels, while the MAX20029B/MAX20029D

has two 0.5A/1.5A channels and by combining channels

1 and 2, a single 2A/3A channel. The PMICs operate from

3.0V to 5.5V, making them ideal for automotive point-of-

load and post-regulation applications.

FETs

Channels

● Designed to Improve Automotive EMI Performance

• Forced-PWM Operation

• Two Channels 180º Out-of-Phase

• SYNC Input

The PMICs feature fixed-frequency PWM-mode operation

with a switching frequency of 2.2MHz. High-frequency

operation allows for an all-ceramic capacitor design

and small-size external components. The low-resistance

on-chip switches ensure high efficiency at heavy loads

while minimizing critical inductances, making the layout

a much simpler task with respect to discrete solutions.

Internal current sensing and loop compensation reduce

board space and system cost.

• Spread-Spectrum Option

● Soft-Start and Supply Sequencing Reduces Inrush

Current

● Individual Enable Inputs and Power-Good Outputs to

Simplify Sequencing

● OV Input-Voltage Monitoring

● Overtemperature and Short-Circuit Protection

● 28-Pin (5mm x 5mm x 0.8mm) TQFN-EP Package

● -40ºC to +125ºC Operating Temperature Range

The PMICs offer a spread-spectrum option to reduce

radiated emissions. Two of the four buck converters

operate 180º out-of-phase with the internal clock. This

feature reduces the necessary input capacitance and

improves EMI as well. All four buck converters operate in

constant PWM mode outside the AM band. The PMICs

offer a SYNC input to synchronize to an external clock.

Ordering Information appears at end of data sheet.

The PMICs provide individual enable inputs and power-good/

reset outputs, as well as factory-programmable PG times.

The PMICs offer several important protection

features including: input overvoltage protection, input

undervoltage lockout, cycle-by-cycle current limiting, and

overtemperature shutdown.

The MAX20029/MAX20029B/MAX20029C/MAX20029D

PMICs are available in a 28-pin TQFN package with an

exposed pad and are specified for operation over the

-40ºC to +125ºC automotive temperature range.
