Maxim Synchronous DC-DC Regulator Delivers Up to 3A in 3 x 3mm Package

Maxim Integrated Products introduced the MAX15041, a synchronous dc-dc converter with integrated MOSFETs in a small 3 x 3mm package. The built-in MOSFETs offer higher efficiency (93%) than asynchronous solutions, while simplifying design and minimizing EMI. Capable of delivering up to 3A, the MAX15041 is well suited for a variety of point-of-load applications including telecom and networking equipment, as well as low-cost consumer products.

This device operates from a fixed 350kHz PWM frequency and utilizes 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 prebiased output.

The MAX15041 operates from a 4.5 to 28V input voltage and provides ±1% output-voltage accuracy over temperature. Available in a space-saving, 3 x 3mm, 16-pin TQFN package, the device is fully specified over the -40 to +85°C extended temperature range. Prices start at $1.80 (1000-up, FOB USA).
