Quick View Data Sheet for the MAX4130
Technical Support: Power
This circuit uses the MAX668 and a transformer (which will need about a one-to-six turns raTIo) to make a flyback converter. The op amp inverts the feedback from the negaTIve output voltage.
The circuit above generates -30V at 80mA from a + 5V input with 83% efficiency to power SLIC integrated circuits. Based on a MAX668 transformer flyback application, the circuit employs a custom transformer to generate -30V. A switching frequency of 500kHz allows the use of ceramic output capacitors. By adding a third ceramic output capacitor, the output current can be increased to 120mA.
