The LM43602PWPT is a SIMPLE SWITCHER® Synchronous Step-down Voltage Converter capable of driving up to 2A of load current from an input voltage ranging from 3.5 to 36V. The LM43602 provides exceptional efficiency, output accuracy and dropout 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 a wide range of applications. Discontinuous conduction and automatic frequency modulation at light loads improve light load efficiency. The family requires few external components and terminal arrangement allows simple, optimum PCB layout. Protection features include thermal shutdown, VCC under-voltage lockout, cycle-by-cycle current limit and output short circuit protection.
