Description
The PT4140 power modules are a series of isolated DC/DC converters housed in a low-profile package. Rated for 20 watts or 5A, the series includes standard output voltages ranging from as low as 1.5VDC to 15VDC. The output may be adjusted up to ±10% of nominal. These converters are ideal for Telecom, Industrial, Computer, and other distributed power applications that require i n p u t - t o - o u t p u t isolation. Using multiple PT4140 modules, system designers can implement a complete custom power supply solution. The flexibility of full isolation also allows the input or output to be configured for negative voltage operation. The PT4140 series requires no additional components for proper operation.

Notes: (1) The DC/DC converter will operate at no load with reduced specifications. (2) The Remote On/Off (pin 1) has an internal pull-up, and if it is left open circuit the module will operate when input power is applied. Refer to the application notes for interface considerations. (3) See Safe Operating Area curves or contact the factory for the appropriate derating.
