各位高手請幫設計兩款變壓器
Input voltage: min 10 - max 15V DC
Output voltage: 35.8V DC +/- 5%
Output current: min 10mA - max 180mA DC
Switching frequency: 262kHz ( We plan to use MAX5053 from Maxim with an external Mosfet: STD5N20 )
switching frequency is 262kHz
第二款:
Project EC Controller:
Input: 180V to 265V AC
Output1: +24VDC +/- 15% (ripple 100mV p-p), 20 to 250mA
Output2: +3.3VDC +/- 5% (ripple 50mV p-p), 100 to 1000mA
Output3: -5VDC +/- 15% (ripple 50mV p-p), 10 to 20 mA
We plan to use a Power-Integrations IC with switching frequency of 132kHz.
多謝!
