The point-of-load applications include those found in telecom, networking, storage, and server equipment.
User-selectable, fixed-frequency PWM, and pulse-skipping modes ensure high efficiency during light loads, while integrated low-resistance MOSFETs maximize conversion efficiency at heavy loads.
The MAX15038/MAX15039 integrates a high-bandwidth (28MHz) voltage-error amplifier, which can be combined with voltage-mode control architecture to enable the implementation of type III compensation. This topology maximizes bandwidth, improves transient response, and minimizes output capacitance, thus allowing an all-ceramic-capacitor design.
These devices operate from a 2.9V to 5.5V supply, and provide ±1% output-voltage accuracy over line, load, and temperature variations. Other features include two 3-state inputs to select one of nine preset outputs, an external reference input for tracking applications, programmable soft-start, and the ability to sink and source current at the output for memory applications. Additionally, the output voltage can be adjusted to any customer value with two external resistors.
The MAX15038/MAX15039 are available in a space-saving, 4mm x 4mm TQFN package, and are fully specified over the -40°C to +85°C extended temperature range. Prices start at $2.73 (1000-up, FOB USA).
