P6140

The P6140 is designed as a planar power transformer using multilayer PCB technology. It is intended for low profile high frequency discontinuous flyback DC-DC converters up to 500kHz. With careful design, output power exceeding 20W is achievable. P6140 has split primaries that can be configured in series or parallel for nominal 48V and 24V systems respectively, with nominal 15V output. The recommended input voltage range is 18V to 70V. Additionally, an auxiliary winding is provided on the primary side.

P6140 has eight features. (1)Planar windings. (2)4mm height above PCB. (3)Low leakage inductance. (4)High frequency operation. (5)Externally configurable. (6)18-70V input capability. (7)Auxiliary winding. (8)Lead-free (Pb-free). Those are all the main features.

Some absolute maximum ratings of P6140 have been concluded into several points as follow. (1)Its short term isolation voltage would be 500Vrms. (2)Its peak primary current would be 8A (primaries in series) and 16A (primaries in parallel; 8A per primary winding). (3)Its V.us per primary winding would be 24V.us (for B=200mT). (4)Its storage temperature would be +85°C. (5)Its magnetic core temperature would be 120°C. (6)Its reflow temperature 10s would be 260°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of P6140 are concluded as follow. (1)Its promary inductance would be min 2.4uH and typ 2.8uH and max 3.25uH. (2)Its leakage inductance would be max 100nH. (3)Its primary/secondary voltage isolation would be min 500Vrms. (4)Its interwinding capacitance would be typ 325pF. (5)Its total transformer losses would be typ 0.6W. (6)Its DCR would be min 12mohms and typ 16mohms and max 20mohms. (7)Its turns ratio would be typ 1.0. (8)Its operating temperature range would be from -40°C to +85°C. And so on.
