5 A of load current from an input voltage ranging from 3.
5 V to 36 V (42 V transient).
The LM43600 provides exceptional efficiency, output accuracy and drop-out 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.
