The LM43600-Q1 regulator is an easy-to-use synchronous step-down DC-DC converter capable of driving up to 0.5 A of load current from an input voltage ranging from 3.5 V to 36 V (42 V transient). The LM43600-Q1 provides exceptional efficiency, output accuracy and dropout voltage in a very small solution size. An extended family is available in 1 A, 2 A, and 3 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 undervoltage lockout, cycle-by-cycle current limit, and output short-circuit protection. The LM43600-Q1 device is available in the 16-pin, leaded HTSSOP (PWP) package (6.6 mm × 5.1 mm × 1.2 mm) with 0.65-mm lead pitch. The device is pin-to-pin compatible with the LM4360x and LM4600x families. The LM43600A-Q1 version is optimized for PFM operation and recommended for new designs.
