MAX20471/MAX20472

Low-Voltage Synchronous

Boost Converter

General Description

Beneﬁts and Features

● Synchronous Boost Converter

The MAX20471 and MAX20472 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 temperature ranges.

• 3.8V to 5.25V Factory-Preset Output in

50mV Steps

• 500mA or 1A Output Versions

● 3.0V to 4.0V Operating Supply Voltage

● True Output Shutdown

● 2.2MHz Switching Operation

● Open-Drain Reset Output Pin (RESET)

● Spread-Spectrum Enable Pin (EN)

● High Precision

The ICs feature a 2.2MHz fixed-frequency, forced pulse-

width modulation (FPWM) mode for better noise immunity

and load-transient response, as well as a pulse-frequency

modulation (skip) mode for increased efficiency during

light-load operation. The 2.2MHz frequency operation

enables the use of all-ceramic capacitors and minimizes

external components. The programmable spread-spectrum

frequency modulation minimizes radiated electromagnetic

• ±1.5% Output-Voltage Accuracy

• 93 ±2% Undervoltage Monitoring

• 107 ±2% Overvoltage Monitoring

• Good Load-Transient Performance

emissions. Integrated low R

switches improve effi-

DS(ON)

ciency at heavy loads, which make the layout a much sim-

pler task with respect to discrete solutions.

● Robust for the Automotive Environment

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

Operation

• Overtemperature and Overcurrent Protection

• 12-Pin (3mm x 3mm) TDFN

Other features of the parts include true output shutdown,

soft-start ramping, overcurrent limiting, and overtempera-

ture protection.

• 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
