应用须知
- AN-2077 LM20k POL Module (Rev. A)PDF, 1.3 Mb, 修订版: A, 档案已发布: 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, 修订版: A, 档案已发布: May 3, 2013
This application note discusses the design options using the high performance 4A synchronous buckconverters, LM20124, LM20134, and LM20144.
