摘　　要：介绍了双路输出、双路闭环控制脉宽调制器UCC2810的功能和电路设计、功率转换电路设计。与单路闭环控制或间接稳压方案相比较,采用UCC2810设计的双路输出DC/DC模块,从根本上消除了交叉调整率的影响,适用于负载不平衡的应用。具有功耗低、电路设计一致性好等优点。This essay introduces the function of dual output and closed-loop control PWM Ucc2810 as well as the design of circuit and power conversion.Comparing with single closed-loop control or indirect stable voltage project,dual output DC/DC power module with Ucc2810 design totally eliminates the influence of cross regulation and can be used in unbalance load condition.It has many advantages like low power and better consistency of circuit design.

关 键 词：多路输出 交叉调整率 双闭环PWM
