The document introduces the PT6640 series of products, which is a positive input to negative output linear switch regulator. The input voltage range is +8V to +25V, the output voltage is adjustable, and the output voltage is -2.5V/4A to -15V/1.5A. The efficiency is as high as 85% and remote sensing is realized.
The PT6640 series consists of positive input to negative output line integrated switching regulators (ISRs) designed for general-purpose applications. The devices deliver up to 24W of negative output power with an efficiency of up to 85% and include remote sense capability. They are available in a 14-pin SIP package or surface-mount configuration.
