The LMR60406 is a 3V to 36V (42V transient), 0.6A, industrial-grade synchronous buck converter in an ultra compact 2.5mm × 2mm QFN-9 package. The HotRod™ QFN package with mitigated interference and noise technology using architecture 1 features (MINT 1) enables low EMI performance to facilitate qualification of industrial and other noise-sensitive designs.

All device variants are capable of output voltages ranging from 1V to 20V in adjustable output configuration. Each variant is also capable of delivering a fixed output voltage by connecting the output voltage node directly to the feedback pin. The Device Comparison table provides details on the fixed output voltage options. The current-mode control architecture with 30ns minimum on time allows high conversion ratios at high frequencies, fast transient response, and excellent load and line regulation.

Open drain power-good output facilitates power sequencing requirements. The MODE/SYNC pin of the LMR60406 allows the user to select between forced pulse width modulation (FPWM), auto mode, or external synchronization mode of operation.

The LMR60406 is designed to offer reduced output capacitance leading to compact PCB layout and system cost savings. The LMR60406 is a part of a family of pin-compatible devices ranging in current levels from 0.6A to 6A.
