In modern electronic devices, AC/DC converters play a crucial role by converting alternating current (AC) to direct current (DC) for various equipment. The FSCQ1265RTYDTU, as a high-performance AC/DC converter, integrates multiple advanced functions and technologies, making it excel in numerous applications. This article will provide a detailed introduction to the key features and specifications of the FSCQ1265RTYDTU, so that readers can better understand the advantages and applicable scenarios of this product.
The FSCQ1265RTYDTU is a high-efficiency AC/DC controller and voltage regulator chip produced by Fairchild Semiconductor. It adopts a compact TO-220F package with five pins, featuring excellent heat dissipation performance. This converter not only supports a wide input voltage range (85V～265VAC) but also boasts high power density and efficiency, making it an ideal choice for various electronic devices.
Efficient Power Conversion
The FSCQ1265RTYDTU can deliver a frame power of up to 170W (at 230VAC ± 15%) and 140W within the input voltage range of 85V～265VAC. In terms of efficiency, the converter achieves 80%～83% efficiency at full load, significantly reducing energy waste.
Pulse Width Modulation (PWM) Control
The FSCQ1265RTYDTU integrates a PWM controller and a high-power Sense FET field-effect transistor, enabling precise control of output voltage and current. PWM technology not only enhances power supply stability but also reduces electromagnetic interference and switching noise.
Multiple Protection Functions
To ensure stable operation of the equipment, the FSCQ1265RTYDTU is equipped with multiple protection functions, including overload protection (OLP), abnormal over-current protection (AOCP), over-voltage protection (OVP), and thermal shutdown (TSD). Among them, OLP and OVP are automatic restart mode protections, while TSD and AOCP adopt latch-off protection forms. These protective measures effectively prevent equipment damage caused by power anomalies.
Advanced Burst Mode
To reduce standby power consumption, the FSCQ1265RTYDTU adopts an advanced burst mode. In standby mode, the converter's power consumption is less than 1W, significantly reducing energy waste.
Wide Input Voltage Range
The FSCQ1265RTYDTU can adapt to a wide input voltage range, making it capable of operating normally under different grid conditions in various countries and regions. Additionally, it features an extended quasi-resonant switching function, further improving power supply adaptability and stability.
Low Startup and Operating Currents
The converter's startup current is only 25μA, and the typical operating current is 6mA. These low-power characteristics enable the FSCQ1265RTYDTU to save significant energy during prolonged operation, reducing the operating costs of the equipment.
