资 源 简 介
The LM20343 is a full featured synchronous buck regulatorcapable of delivering up to 3A of load current. The currentmode control loop is externally compensated with only twocomponents, offering both high performance and ease of use.The device is opTImized to work over the input voltage rangeof 4.5V to 36V making it well suited for high voltage systems.The device features internal Over Voltage ProtecTIon (OVP)and Over Current ProtecTIon (OCP) circuits for increased systemreliability. A precision Enable pin and integrated UVLOallows the turn on of the device to be TIghtly controlled andsequenced. Startup inrush currents are limited by both an internallyfixed and externally adjustable soft-start circuit. Faultdetection and supply sequencing are possible with the integratedpower good (PGOOD) circuit.
