MAX20472B

Low-Voltage Synchronous Boost Converter

General Description

Benefits and Features

The MAX20471, MAX20472, and MAX20472B are high-

efficiency low-voltage DC-DC converters that boost a 3.0V

to 4.0V input supply to between 3.8V and 5.25V (factory-

configurable) at 500mA or 1A. The boost converters

achieve ±1.5% output error over load, line, and tempera-

ture range.

● Multiple Functions for Small Size

• Synchronous Boost Converter

• 3.8V to 5.25V Factory-Preset Output in 50mV

Steps

• 500mA and 1A Options

• 3V to 4V Operating Supply Voltage

• True Output Shutdown

• 2.2MHz Operation for the MAX20471/MAX20472

• 2.0MHz Operation for the MAX20472B

• Open-Drain Reset Output Pin (RESET)

• Spread-Spectrum Enable Pin (SSEN)

The devices feature a 2.2MHz (2.0MHz for MAX20472B)

fixed-frequency PWM mode for better noise immunity and

load-transient response, and a pulse-frequency modula-

tion mode (skip) for increased efficiency during light-load

operation. The 2.2MHz/2.0MHz frequency operation al-

lows for the use of all ceramic capacitors and minimizes

external components. The programmable spread-spec-

trum frequency modulation minimizes radiated electro-

● High Precision

• ±1.5% Output Voltage Accuracy

• 93 ±2% UV Monitoring

magnetic emissions. Integrated low-R

prove efficiency at heavy loads and make the layout a

much simpler task with respect to discrete solutions.

switches im-

• 107 ±2% OV Monitoring

• Good Load-Transient Performance

DSON

● Robust for the Automotive Environment

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

• Overtemperature and Short-Circuit Protection

• 12-Pin (3mm x 3mm) TDFN

Other features include True Shutdown™, soft-start, over-

current, and overtemperature protections.

• 12-Pin (3mm x 3mm) SWTDFN

• 8-Pin (0.150") SOIC (MAX20471 Only)

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

Applications

● Automotive Point of Load

● Automotive CAN Transceivers
