Description

The UTC UC3875 is a high performance current mode PWM controller ideally suited for low standby power. The PWM switching frequency is programmable the UC3875 does not provide. The ISL6551 enables a complete and sophisticated power supply solution and can save board space and engineering effort as This Application Note will highlight the design considerations incurred in a high frequency power supply using the Phase Shifted Resonant PWM control Voltage Transition Design Considerations and the UC3875 PWM Controller ( SLUA107).
