MAX20471/MAX20472/B Low-Voltage Boost Converters

Analog Devices Inc. MAX20471/MAX20472/B Low-Voltage Synchronous Boost Converters boost a 3.0V to 4.0V input supply to between 3.8V and 5.25V (factory configurable) at 500mA, 1A, or 2A. The boost converters achieve ±1.5% output error overload, line, and temperature ranges. The ICs feature a 2.2MHz fixed-frequency, forced pulse-width modulation (FPWM) mode for better noise immunity and load-transient response. It also has 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 emissions. Integrated low R_DS(ON) switches improve efficiency at heavy loads, making the layout much simpler than discrete solutions. Other features of the parts include true output shutdown, soft-start ramping, overcurrent limiting, and overtemperature protection.
