The MAX15041 from Maxim is a synchronous DC-DC converter with integrated MOSFETs in a small 3 x 3 mm package. The built-in MOSFETs offer high efficiency (93%) while simplifying design and minimising EMI. Capable of delivering up to 3 A, the IC is suited for a variety of point-of-load applications including telecom and networking equipment, as well as low-cost consumer products.
The device operates from a fixed 350 kHz PWM frequency and utilises a peak-current-mode architecture to simplify compensation. This topology ensures excellent load transient response, thus enabling an all-ceramic-capacitor design. Other features include an enable input and power-good indicator. This converter also offers the ability to safely start up into a pre-biased output. The MAX15041 operates from a 4,5 V to 28 V input voltage and provides ±1% output-voltage accuracy over temperature.
