LM61495RPHEVM Synchronous Step-Down Voltage Converter

The LM61495-Q1 is an easy-to-use synchronous step-down DC-DC converter capable of driving up to 10 A of load current from a supply voltage ranging from 3 V to 36 V. The LM61495-Q1 provides exceptional efficiency and output accuracy in a very small solution size. The LM61495-Q1 implements peak-current-mode control. Additional features such as adjustable/synchronizable switching frequency, pin selectable dual-random spread spectrum (DRSS), true slew rate control, FPWM/AUTO selection, power-good/RESET flag, and precision enable provide both flexible and easy-to-use solutions for a wide range of applications. Automatic frequency foldback (AUTO mode) at light load and optional external bias improve efficiency over the entire load range. The device family requires few external components and has a pinout designed for simple PCB layout with excellent EMI and thermal performance. Protection features include thermal shutdown, input undervoltage lockout, cycle-by-cycle current limiting, and hiccup short-circuit protection. The LM61495-Q1 is pin-to-pin compatible with LM62460-Q1 and LM61480-Q1 for easy current scaling.

The pin configuration of the LM61495-Q1 is shown in Figure 1-1.
