LM46001PWPT

LM4600x/LM4600x-Q1 Step-Down Voltage Converter

Texas Instruments LM4600x/LM4600x-Q1 SIMPLE SWITCHER® Regulators are an easy-to-use synchronous step-down DC-DC converter capable of driving up to 2A of load current from an input voltage range of 3.5V to 60V. The LM4600x/LM4600x-Q1 provides exceptional efficiency, output accuracy, and drop-out voltage in a very small solution size. Peak current-mode control is employed to achieve simple control loop compensation and cycle-by-cycle current limiting. Optional features such as programmable switching frequency, synchronization, power-good flag, precision enable, internal soft-start, extendable soft-start, and tracking provide a flexible and easy-to-use platform for various applications. Discontinuous conduction and automatic frequency modulation at light loads improve light load efficiency. The Texas Instruments LM4600x/LM4600x-Q1 requires few external components, and pin arrangement allows a simple optimum PCB layout. Protection features include thermal shutdown, V_CC under-voltage lockout, cycle-by-cycle current limit, and output short circuit protection.
