Texas Instruments LM43603PWPT

The LM43603 SIMPLE SWITCHER® regulator is an easy to use synchronous step-down DC-DC converter capable of driving up to 3 A of load current from an input voltage ranging from 3.5 V to 36 V (42V abs max). The LM43603 provides exceptional efficiency, output accuracy and dropout voltage in a very small solution size. An extended family is available in 0.5 A ,1 A and 2 A load current options in pin to pin compatible packages. 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 pin 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. The LM43603 device is available in the HTSSOP / PWP 16 leaded package (5.1mm x 6.6mm x 1.2mm) and VSON-16 package with wettable flanks. HTSSOP package will be pin to pin compatible with LM43600, LM43601, LM43602, LM46000, LM46001, LM46002. VSON-16 package will only be pin to pin compatible with LM43602.
