LM43602AQPWPTQ1

The LM43602AQPWPTQ1 regulator is an easy-to-use synchronous step-down DC-DC converter capable ofdriving up to 2 A of load current from an input voltage ranging from 3.5 V to 36 V (42-V absolutemaximum). The LM43602AQPWPTQ1 provides exceptional efficiency, output accuracy, and dropout voltage in avery small solution size. An extended family is available in 0.5-A, 1-A, and 3-A load currentoptions in pin-to-pin compatible packages. Peak current-mode control is employed to achieve simplecontrol loop compensation and cycle-by-cycle current limiting. Optional features such asprogrammable switching frequency, synchronization, power-good flag, precision enable, internal softstart, extendable soft start, and tracking provide a flexible and easy-to-use platform for a widerange of applications. Discontinuous conduction and automatic frequency modulation at light loadsimprove light-load efficiency. The family requires few external components and terminal arrangementallows simple, optimum PCB layout. Protection features include thermal shutdown,VCC undervoltage lockout, cycle-by-cycle current limit, and output shortcircuit protection. The LM43602AQPWPTQ1 device is available in a 16-lead HTSSOP package (5.1 mm × 6.6 mm ×1.2 mm) and 16-pin VSON package with wettable flanks.
