Holtek Semiconductor HT7A4001F
The HT7A4001N/HT7A4001H/HT7A4001F are highly integrated flyback controllers that achieve high efficiency, low power consumption and cost-effective for switching mode power supply (SMPS). The controllers integrate the multi-mode operation for different output loads to optimize the system efficiency. The controllers also have an integrated frequency jitter to reduce the EMI emissions and simplify EMI filter design.| Part No. | HT7A4001F |
