LM20123M Datasheet

DC/DC Switching Converters


The LM20123M is a full featured 1.5 MHz synchronous buck regulator capable of delivering up to 3A ofcontinuous output current. The current mode control loop can be compensated to be stable with virtually any type of output capacitor. For most cases, compensating the device only requires two external components, providing maximum flexibility and ease of use. The device is optimized to work over the input voltage range of 2.95V to 5.5V making it suited for a wide variety of low voltage systems. LM20123M Features • LM20123Q is AEC-Q100 Qualified • Accurate Current Limit Minimizes Inductor Size• 96% Efficiency with 1.5 MHz Switching Frequency• Starts up into Pre-Biased Loads• Output Voltage Tracking• Peak Current Mode Control• Adjustable Soft-Start with External Capacitor• Precision Enable Pin with Hysteresis LM20123M Applications • High Performance DSPs, FPGAs, ASICs and Microprocessors• Broadband, Networking and Optical Communications Infrastructure
