(Reference the applicable package code draw- ing for the dimensions and PC board layout) Description The PT6620 series is a line of 12-V input Integrated Switching Regulators (ISRs). These regulators are designed for stand-alone operation in applications requiring as much as 6 A of output current. The PT6620 series is pack- aged in a 14-Pin SIP (Single In-line Package), which is available in either a vertical or horizontal configura- tions, including surface mount.
