3 Description
The LM5149-Q1 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 LM5149-Q1 can be set up in dualphase
mode with accurate current sharing for highcurrent
applications. It can operate with VIN as low as
3.5 V, at nearly 100 duty cycle if needed.
The LM5149-Q1 has two unique EMI reduction
features: active EMI filter and dual random spread
spectrum (DRSS). The active EMI filter senses
any noise or ripple voltage on the DC input
bus and injects an out-of-phase cancellation signal
to reduce the disturbance. DRSS combines lowfrequency
triangular and high-frequency randomized
modulations to mitigate EMI across lower and higher
frequency bands, respectively. This hybrid technique
aligns with the multiple resolution bandwidth (RBW)
settings specified in industry-standard EMC tests.
