The LMR60440-Q1 is a 3V to 36V (42V transient), 4A, automotive-grade synchronous buck converter. The LMR60440-Q1 is available in an ultra compact 2.5mm × 2mm HotRod™ QFN-9 package or 3.5mm × 2.5mm HotRod ™QFN-11 packagewith wettable flanks available, that helps minimize inductance and achieve low EMI performance to facilitate qualification of automotive 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 LMR60440-Q1 allows the user to select between forced pulse width modulation (FPWM), auto mode, or external synchronization mode of operation.
The LMR60440-Q1 is designed to offer reduced output capacitance leading to compact PCB layout and system cost savings. The LMR60440-Q1 is a part of a family of pin-compatible devices ranging in current levels from 0.6A to 6A.
