Hvled001btr STMicroelectronics hvled001b high power factor flyback controller

Oelectronics hvled001b high power factor flyback controller is an enhanced peak current mode controller, which can focus on controlling high power factor (HPF) flyback or buck boost. Hvled001b can also be used to implement other topologies, such as Buck, boost and SEPIC. With the help of hvled001b, the primary side regulation and optocoupler control can be applied independently, and the precise regulation and extremely low standby power consumption can be realized under no-load conditions. St high voltage technology supports the direct connection of hvled001b to the input voltage to start the device and monitor the input voltage without external components. Hvled001b can provide protection against abnormal conditions, including open circuit, output short circuit, input overvoltage and undervoltage. Circuit faults such as open-loop and overcurrent of the main switch can also be effectively controlled. Hvled001b also integrates the automatic recovery timer (Art) function to ensure automatic recovery of applications without reducing reliability. The primary side voltage regulator of characteristic quasi resonant (QR) topology output voltage is directly connected to the optocoupler. Through feedback disconnection detection, the current loop regulation is realized. 800V high voltage start-up is realized in the general range, high power factor and low THD are realized. It has high efficiency and output stability in a wide range of voltage and current. It has very low no-load standby power consumption and programmable frequency turn back

Oelectronics hvled007 current mode PFC controller adopts special circuit (input current shaper) to support high PF quasi resonant flyback converter to obtain theoretical sinusoidal input current from power line. The IC has a control input to be driven by the phototransistor of the optocoupler to close the isolated control loop of the secondary side voltage stabilization. However, by adding a simple external circuit, it can also be used to close the voltage loop of the primary side regulator. Hvled007 has various protection features and can handle overload, short circuit and overvoltage. The output stage of push-pull output circuit has the ability of 600mA pull current and 800mA fill current, which is suitable for large MOSFET Drivers. Thanks to the push-pull output circuit level and other characteristics, the device becomes a low-cost solution very suitable for SMPS (up to 100W) conforming to en61000-3-2 standard. The hvled007 PFC controller is ideal for indoor and outdoor solid-state lighting applications, with an extended operating temperature range as low as – 40 ° C and guaranteed electrical specifications. Characteristics: the flyback PFC pre regulator is converted to mode (quasi resonant) control. The proprietary input current shaper can realize the minimum line current thd.
