Application Notes
- AN-2077 LM20k POL Module (Rev. A)PDF, 1.3 Mb, Revision: A, File published: May 3, 2013
The LM20k is a full-featured synchronous buck switching regulator capable of driving up to 6A of loadcurrent and converting an input voltage between 2.95V and 5.5V down to an output voltage as low as0.8V. Fault protection features include cycle-by-cycle current limit, output power good, and output overvoltageprotection. The dual function soft-start/tracking pin can be used to control the sta - AN-1751 4A LM20k Reference Designs (Rev. A)PDF, 215 Kb, Revision: A, File published: May 3, 2013
This application note discusses the design options using the high performance 4A synchronous buckconverters, LM20124, LM20134, and LM20144. - AN-1747 3A LM20k Reference Designs (Rev. A)PDF, 242 Kb, Revision: A, File published: May 3, 2013
The LM20123, LM20133, and LM20143 are a full-featured family of high performance 3A synchronousbuck converters. These devices are tailored to operate over an input voltage range of 2.95 V to 5.5 V andeach can be optimized to meet many different performance requirements. The LM20123 operates at afixed frequency and only requires 11 components to generate a solution. The LM20143 is similar to - Powering FPGAs Using LM201xx PowerWise Synchronous Buck Regulators (Rev. A)PDF, 45 Kb, Revision: A, File published: May 3, 2013
