Description
The chip integrates high-voltage POWERMOS to meet the requirements of low power consumption. In standby mode, the power consumption is reduced by reducing the operating frequency while outputting a stable operating voltage. Frequency reduction is limited below 20KHz/21.5KHz to avoid audible noise. In failure modes such as open loop, overvoltage or overload caused by short circuit, the chip switches to restart mode through the internal protection circuit. Through the internal precise current peak control, the size of the transformer and the size of the secondary diode can be made smaller, thereby reducing the overall system cost. […]
