Data Sheet

MAX20015–MAX20018

Single 2.2MHz, Low-Voltage, Step-Down DC-DC Converter Family for Safety Applications

General Description

Beneﬁts and Features

● High Feature Set in Ultra-Small Footprint

• High-Eﬃciency DC-DC Converter

• Up to 3A Output Current

The MAX20015–MAX20018 family of ASIL B-compliant

high-efficiency switching regulators delivers up to 3A load

current from 0.5V to 3.8V. The devices operate from a 2.7V

to 5.5V input voltage range, making them ideal for on-board

point-of-load and post-regulation applications. Total output

error is less than ±1.5% over load, line, and temperature.

• 2.7V to 5.5V Operating Supply Voltage

• Resistor-Adjustable or Factory-Preset Output Voltages

• Synchronizable, 2.2MHz Switching Frequency

• Enable Input

• RESET Output•Spread-Spectrum Enable Input

• Forced-PWM and Skip Modes

The devices feature fixed-frequency PWM mode operation,

with a 2.2MHz switching frequency. High-frequency operation

allows for an all-ceramic capacitor design and small external

components.

• Current-Mode Architecture

• 3mm x 3mm x 0.85mm 10-Pin TDFN

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.

Following a simple layout and footprint ensures first-pass suc-

cess in new designs.

● High Precision

• Selectable Overvoltage/Undervoltage Thresholds

• ±1.5% OV/UV Accuracy

• ±1.5% Output-Voltage Accuracy

• Excellent Load-Transient Performance

• Overtemperature and Short-Circuit Protection

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

The devices provide an enable input, spread-spectrum enable

input, and RESET output. The output voltage can be preset at

the factory to allow customers to achieve ±1.5% output-volt-

age accuracy without using expensive 0.1% resistors. In addi-

tion, the output voltage can be set to any customer value by

using two external resistors at the feedback, with 0.5V internal

reference. The devices offer factory-programmable soft-start

and RESET hold times.

● Diagnostics and Redundant Circuits

• ASIL B Compliant

• Redundant Reference

• Shorted Pin Detection on RESET

The 10-pin TDFN exposed pad devices include overtem-

perature shutdown and overcurrent limiting. All devices are

designed to operate over the -40°C to +125°C ambient tem-

perature range.

Applications

● Automotive

● Point-of-Load (PoL)
