MAX20412

Automotive Low-Voltage, 2-Channel

Step-Down Controller

General Description

Beneﬁts and Features

● 2-Channel, High-Efficiency DC-DC Controller in a

The MAX20412 is a dual-output, high-efficiency, synchro-

nous step-down controller IC that operates with a 3.0V to

5.5V input voltage range and provides a 0.25V to 1.275V

output voltage range. The controller architecture enables

up to 30A of load current per phase. Channel one has an

option to operate with two phases to deliver higher load

current, making this device ideal for automotive point-of-

load (PoL) and post-regulation applications.

Small Solution Size

• 3.0V to 5.5V Operating Supply Voltage

• OUT1 Supports 60A (with Two Phases)

• OUT2 Supports 30A

● High-Precision Regulator for Applications Processors

• ±2% Output-Voltage Accuracy

• Diﬀerential Remote-Voltage Sensing

• I C-Controlled Output Voltage: 0.25V to 1.275V in

The IC achieves ±2% output error over load, line, and

temperature ranges. The IC features a 2.2MHz/1.1MHz

fixed-frequency PWM mode for better noise immunity

and load-transient response, and a pulse-frequency

modulation mode (skip) for increased efficiency during

light-load operation. The 2.2MHz frequency operation

allows the use of all-ceramic capacitors and minimizes

externalcomponents.Theprogrammablespread-spectrum

frequency modulation minimizes radiated electromagnetic

emissions.

6.25mV Steps

• Excellent Load-Transient Performance

• Programmable Compensation

● Low-Noise Features Reduce EMI

• 2.2MHz or 1.1MHz Operation

• Spread-Spectrum Option

• Frequency-Synchronization Input/Output

• Current-Mode, Forced-PWM, and Skip Operation

● Robust for the Automotive Environment

• Individual Enable Inputs and PGOOD Outputs

The MAX20412 is offered with factory-preset output

voltages (see the Selector Guide for options). The I C

• Low R

External MOSFETs

DS(ON)

• Overtemperature and Short-Circuit Protection

• 32-Pin (5mm x 5mm) TQFN with Exposed Pad

• -40°C to +125°C Operating Temperature Range

• AECQ-100 Qualiﬁed

interface supports dynamic voltage adjustment with pro-

grammable slew rates for each channel. Other features

include programmable soft-start, overcurrent, and over-

temperature protections.
