The LM5148 is a 80-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 LM5148 can be set up in idual-phase 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.The LM5148 has a unique EMI reduction feature known as dual random spread spectrum (DRSS). Combining low-frequency triangular and high-frequency random modulations mitigates EMI disturbances across lower and higher frequency bands, respectively. This hybrid technique aligns with the multiple resolution bandwidth (RBW) settings specified in industry-standard EMC tests.
