More Information

The LM25148 is a 42-V, ultra-low IQ synchronous buck DC/DC controller for high-current, single-output applications. The controller uses a peak current-mode control architecture for easy loop compensation, fast transient response, and excellent load and line regulation. The LM25148 can be set up in interleaved mode (paralleled output) with accurate current sharing for high-current applications. It can operate at input voltages as low as 3.5 V, at nearly 100% duty cycle if needed.
