美国国家半导体公司(National Semiconductor)推出一款可支持高效系统的迟滞P场效应晶体管(P-FET)降压控制器。这款型号为LM3475的控制器芯片采用极小巧SOT23-5封装,其特点是设有可以精简系统设计的迟滞控制电路。如果系统设计人员采用这款芯片便无需为系统提供外部补偿,确保多种不同元件稳定操作,以便系统做出快速瞬态响应。迟滞控制电路在极小负载下也
National Semiconductor introduced a hysteretic P-FET buck controller that supports efficient systems. The LM3475 controller chip is housed in a tiny SOT23-5 package featuring a hysteretic control circuit that simplifies system design. System designers using the chip eliminate the need for external compensation for the system, ensuring stable operation of many different components so that the system can make fast transient response.
