应用须知
- AN-1487 Current Mode Hysteretic Buck Regulators (Rev. B)PDF, 158 Kb, 修订版: B, 档案已发布: May 5, 2013
Texas Instruments has developed a family of peak current mode hysteretic buck regulator controllers(such as the LM27212, the LM27213, and the LM27292, and so forth). This architecture has somecharacteristics that differ from its PWM counterpart. This application report highlights some of theseunique characteristics and discusses the tradeoffs involved.
