Description

The LM43603 regulator is an easy-to-use synchronous step-down DC-DC converter capable ofdriving up to 3 A of load current from an input voltage ranging from 3.5 V to 36 V (42 V abs max).The LM43603 provides exceptional efficiency, output accuracy and dropout voltage in a very smallsolution size. An extended family is available in 0.5-A, 1-A, and 2-A load current options in pinto pin compatible packages. Peak current mode control is employed to achieve simple control loopcompensation and cycle-by-cycle current limiting. Optional features such as programmable switchingfrequency, synchronization, power-good flag, precision enable, internal soft-start, extendablesoft-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 output shortcircuit protection. The LM43603 device is available in the HTSSOP / PWP 16 leaded package (5.1 mm ×6.6 mm × 1.2 mm) and VSON-16 package with wettable flanks. HTSSOP package is pin-to-pin compatiblewith LM43600, LM43601, LM43602, LM46000, LM46001, LM46002. VSON-16 package is only pin-to-pincompatible with LM43602.
