PQ3056A
High Frequency Quasi-Resonant Flyback Converter
With GaN Integrated
PQ3056A is a high frequency, quasi-resonant flyback PWM converter with 650V GaN integrated (QR/DCM), which can achieve high efficiency and reliability. The converter built-in high voltage start-up circuit through HV pin. Therefore, extremely low standby power consumption and super-fast start-up time can be obtained by HV pin. PQ3056A provides an adaptive switching frequency fold_x0002_back to achieve higher efficiency in the whole loading range. It operates in QR and DCM with valley switching for high efficiency. And at no load, the IC will operate in burst mode to reduce power consumption. PQ3056A provides functions of low start-up current, fast start-up, low standby power consumption. The burst mode with extremely low operation current (350uA) can significantly reduce standby power consumption to meet the efficiency regulations. The converter integrates a segment power supply circuit for VDD power supply, which is especially suitable for applications with wide output voltage range. PQ3056A offers comprehensive protections to prevent the circuit from damage under abnormal conditions. Furthermore, the features of frequency jittering and smart driving function can minimize the noise and improve EMI performance.
