Supply TI LM73605QRNPRQ1 5A Automotive Synchronous Step Down Voltage Converter

Shenzhen Mingjiada Electronics Co., Ltd.——Long Term Supply (TI) LM73605QRNPRQ1 Synchronous Step-Down DC/DC Converters, Below is product information for LM73605QRNPRQ1:

Part Number: LM73605QRNPRQ1
Package: WQFN-30
Type: Automotive Synchronous Step-Down Converters
Product Details: LM73605QRNPRQ1——3.5V to 36V, 5A Automotive qualified synchronous step-down voltage converter.

LM73605QRNPRQ1 is easy-to-use synchronous step-down DC/DC converters capable of driving up to 5A of load current from a supply voltage ranging from 3.5V to 36V.

The LM73605QRNPRQ1 provide exceptional efficiency and output accuracy in a very small solution size. Peak current-mode control is employed. Additional features such as adjustable switching frequency, synchronization to an external clock, power-good flag, precision enable, adjustable soft start, and tracking provide both flexible and easy-to-use solutions for a wide range of applications. LM73605QRNPRQ1 Automatic frequency foldback at light load and optional external bias improve efficiency over the entire load range.

LM73605QRNPRQ1 requires few external components and has a pinout designed for simple PCB layout with optimal EMI and thermal performance. Protection features include thermal shutdown, input undervoltage lookout, cycle-cy-cycle current limiting, and hiccup short-citcuit protection. The LM73605QRNPRQ1 is pin-to-pin compatible for easy current scaling.
