MAX20428

Eight-Output Mini PMIC for ADAS Applications

General Description

Beneﬁts and Features

The MAX20428 is a high-efficiency, eight-output, low-voltage

PMIC. OUT1 boosts the input supply to 5V at up to 500mA,

while three synchronous step-down converters operate from

an input voltage range of 3.0V to 4.2V and provide an output

voltage range of 0.8V to 3.9875V at up to 1.3A peak, 1.3A

peak, and 3.5A peak, respectively. Three 300mA pMOS LDOs

operate from an input voltage range of 2.7V to 5.5V and pro-

vide an output voltage of 0.8V to 3.9875V. A 25mΩ load switch

with soft-start is also included. All regulated outputs achieve

±1.5% DC accuracy over load, line, and temperature range.

● Multiple Functions for Small Size

• Synchronous 5V, 500mA Boost Converter

• Dual 1A Synchronous Buck Converters

- 0.8V to 3.9875V in 12.5mV Steps

- 1.3A Peak Output Capability

• Single 3A Synchronous Buck Converter

- 0.8V to 3.9875V in 12.5mV Steps

- 3.5A Peak Output Capability

• Three 300mA Low-Dropout Linear Regulators

• One 25mΩ Load Switch

• Programmable Challenge/Response Watchdog

• I C Fast-mode Plus Compatible Interface with

Packet-Error Checking (PEC) Option

• 2.1MHz Internal Operation with Spread-Spectrum Option

The device features a 2.1MHz fixed-frequency PWM mode

for better noise immunity and load-transient response. The

2.1MHz frequency operation allows for the use of all ceramic

capacitors and minimizes external components. The pro-

grammable spread-spectrum frequency modulation minimizes

● High-Precision Performance

• ±1.5% Output Voltage Accuracy

• ±1% OV/UV Monitoring

• Excellent Load-Transient Performance

radiated electromagnetic emissions. Integrated low R

switches improve efficiency at heavy loads and simplify the

layout with respect to discrete solutions.

DS(ON)

● Diagnostics and Redundant Circuits

• ASIL C Compliant

The device is offered with factory-preset output voltages. See

the Ordering Information table for options. Other features

include soft-start, overcurrent, and overtemperature protections.

• Redundant Reference

• Fail Safe on Open Pins

• Shorted Pin Detection on RESET

• PV Supply OV/UV Monitor

Applications

● Advanced Driver-Assistance Systems

● Robust for the Automotive Environment

• Current-Mode, Forced-PWM Operation

• Overtemperature and Short-Circuit Protection

• 5mm x 5mm, 28-Pin, Side-Wettable TQFN

• -40°C to +125°C Grade 1 Automotive Temperature
