Details
The TOP246R is a highly integrated switcher IC (integrated circuit) designed for off-line power conversion applications. It incorporates a 700V power MOSFET, PWM control, thermal shutdown, frequency jittering, and an error amplifier with precise internal voltage reference, all into a single IC. This integration allows for a compact and efficient power supply design.The TOP246R operates in conjunction with an external circuitry including a transformer, output diode, output capacitor, and feedback components to regulate the output voltage. It utilizes a pulse width modulation (PWM) control scheme to achieve regulation, which helps in achieving high efficiency and good transient response.Key features of the TOP246R include a wide input voltage range of 85V to 265V, an internal start-up circuit that allows for a fast power supply start-up, and cycle-by-cycle current limit to protect against overloads and short circuits. It also has frequency jittering to reduce EMI emissions and pulse skipping for improved efficiency at light loads.
