SMPS Xfmr Designed in conjunction with ON-Semi, the TO Series of transformers work with the ON Semiconductor NCP1207 PWM

 

TO Series SMPS Xfmr Designed in conjunction with ON-Semi, the TO Series of transformers work with the ON Semiconductor NCP1207 NCP1207 PWM current-mode controller with quasiresonant (QR) switching capability. Standard designs for 5V and 12V single outputs in power levels ranging from 25W to 85W will get your prototypes up and running fast. Just contact ICE Components to request samples or to discuss a custom version to meet your specific requirement.

Measured at 100 kHz, 1 Vrms. Electrical specifications at 25ºC. Meets UL 94V-0. perating temperature range: -40ºC to +130ºC. Operating temperature is the O sum of ambient temperature plus temperature rise. 5. ransformer inductance values calculated using ON Semi-conductor's T "QR Inductance Calculation" spreadsheet, available at http://www.onsemi.com/pub/collateral/QR IND CALC.xls. Certain design assumptions were necessary to develop core and bobbin choices: A. nput bulk capacitor sized at 2 uF/W, rounded up to the first commercially I available value. B. niversal input voltage, with 265 VAC as the upper limit. The lower limit U input voltage was adjusted to cause the input bulk capacitor value to be a commercially available value. C. Maximum switching frequency: 100 kHz. D. E. F. G. Maximum duty cycle:
