LM62460RPHEVM Synchronous Step-Down Voltage Converter

The LM62460-Q1 is an easy-to-use synchronous step-down DC-DC converter capable of driving up to 6 A of load current from a supply voltage ranging from 3 V to 36 V. The LM62460-Q1 provides exceptional efficiency and output accuracy in a very small solution size. The LM62460-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 LM62460-Q1 is pin-to-pin compatible with LM61480-Q1 (8-A converter) and LM61495-Q1 (10-A converter) for easy current scaling.

The pin configuration of the LM62460-Q1 is shown in Figure 1-1.
