LM43600AQPWPTQ1

The LM43600AQPWPTQ1 regulator is an easy-to-use synchronous step-down DC-DC converter capable ofdriving up to 0.5 A of load current from an input voltage ranging from 3.5 V to 36 V (42 Vtransient). The LM43600AQPWPTQ1 provides exceptional efficiency, output accuracy and drop-out voltage in avery small solution size. An extended family is available in 1-A, 2-A and 3-A load current optionsin pin-to-pin compatible packages. Peak current mode control is employed to achieve simple controlloop compensation and cycle-by-cycle current limiting. Optional features such as programmableswitching 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 ofapplications. Discontinuous conduction and automatic frequency modulation at light loads improvelight load efficiency. The family requires few external components and pin arrangement allowssimple, optimum PCB layout. Protection features include thermal shutdown,VCC undervoltage lockout, cycle-by-cycle current limit, and outputshort-circuit protection. The LM43600AQPWPTQ1 device is available in the 16-pin HTSSOP (PWP) leaded package(6.6 mm × 5.1 mm × 1.2 mm) with 0.65-mm lead pitch. Pin-to-pin compatible with LM46000, LM46001,LM46002, LM43601, LM43602, and LM43603 devices.
