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 - Powering FPGAs Using LM201xx PowerWise Synchronous Buck Regulators (Rev.
