IN2P170C1-D7G (DIP-7)
IN2P170C1-S7G (SOP-7)
High Voltage Start-up PWM Flyback (SSR) Power Switch
General Description
IN2P170C1/N is a higher integrated , high voltage start-up of PWM flyback power switch. It provides several functions to enhance the efficiency to meets the criteria of global standards such as DoE Level VI and EU CoC V5 Tier-2. Meantime, it also provides excellent EMI-improved solution, and also built in complete protection.
IN2P170C1/N is a green mode controller, which implements low start-up current, green-mode power-saving. It is also built-in the leading-edge blanking (LEB) of the current sensing and feedback loop to screen the spike noise from any input signal. The internal slope compensation can limit the constant output over universal AC input range. The sawtooth over frequency function for EMI improved solution.
Meanwhile, IN2P170C1/N also provides various protection, such as, OLP (Over Load Protection) ,VDD OVP (Over Voltage Protection) , Output OLP and output OVP to prevent the circuit damage from the abnormal conditions.
IN2P170C1/N is available in DIP-7.
IN2P170C1/N works with current sensing synchronous rectifier controllers, such as IN6R001C or IN6RY01A/B to achieve higher conversion efficiency and very compact power density.
