Description of product

MAX20014 Boost & Dual Step-Down Converters

Maxim MAX20014 Synchronous Boost & Dual Step-Down Converters are high-efficiency three-output low-voltage DC-DC converters. The OUT1 boosts the input supply up to 8.5V at up to 750mA, while two synchronous step-down converters operate from a 3.0V to 5.5V input voltage range and provide a 0.8V to 3.8V output voltage range at up to 3A. The boost converter achieves ±2%, and the buck converters achieve ±1.5% output error overload, line, and temperature range. The device features a 2.2MHz fixed-frequency pulse-width modulation (PWM) mode for better noise immunity and load transient response. It also has a pulse-frequency modulation mode (skip) for increased efficiency during light-load operation. The 2.2MHz frequency operation allows for the use of all-ceramic capacitors and minimizes external components footprint. The programmable spread-spectrum frequency modulation minimizes radiated electromagnetic emissions. Integrated low RDS(ON) switches improve efficiency at heavy loads and make the layout a much simpler task compared to discrete solutions. The device is offered with factory-preset output voltages or resistor-adjustable output voltages. Other features include soft-start, overcurrent, and overtemperature protection.
