Low priced DC-DC synchronous controller with current rating up to 25A

Maxim's new MAX15026 is a low-cost, DC-DC synchronous step-down controller capable of driving external MOSFETs to deliver up to 25A of output current. MAX15026 operates over a wide, 4.5V to 28V input range, allowing it to be used in 5V- or 12V-bus applications. This IC can provide output voltage from 0.6V to 85% of the input voltage.
The parameters such as switching frequency, compensation, and current limit can be adjusted as per designer requirements to get optimum results.
MAX15026 is ideal for high-reliability applications such as telecom, networking, and server equipment. Concurrently, it is cost effective enough to be used in set-top-box and power-module applications.

The MAX15026 uses cycle-by-cycle lossless current sensing to reduce power loss and eliminate the need for an external sense resistor. Other features include soft-start, an analog-enable input, and a power-good indicator. The device also allows monotonic startup into a prebiased bus without discharging the output. The operating temp range covers -40°C to +85°C
