PMIC - AC DC Converters, Offline Switchers

The FSCM0765RJX is a cost-effective integrated solution that combines an AC/DC PWM (Pulse Width Modulation) Boost-buck offline switcher, high-side and low-side MOSFET drivers, integrated TVS (Transient Voltage Suppression) and reverse-current protection functions in a low-profile, moldable 7-pin SP2 package. It is specifically designed to reduce development time and minimize component count in a variety of AC/DC and DC/DC power supplies for signage, industrial, white goods and communication applications. The FSCM0765RJX also integrates EMI (Electromagnetic Interference) filter, thermal protection and short-circuit protection to meet global safety and industry regulations.

Application Field

The FSCM0765RJX is a perfect solution for a variety of AC/DC and DC/DC power supplies for a variety of applications including signage, industrial, white goods, communication and all offline power systems up to 65W, especially those requiring 220/240VAC input. It provides a high level of system integration while meeting the safety and EMI requirements of applications.

Working Principle

The FSCM0765RJX integrates a constant off-time PWM controller based on peak current control technology and an isolated offline flyback converter, both of which provide accurate load and line regulation. It features ultra-low start-up and operating current which can reduce overall system power losses. The device integrates an integrated reverse current protection, an integrated EMI filter, and thermal protection. The device uses a PWM shutdown mode to reduce overall system power losses. Under short-circuit conditions, the PWM frequency is increased to maximize system protection.

The FSCM0765RJX supports a wide range of input voltages from 85VAC to 265VAC. The output voltage can be adjustable from 5V to 20V, with a wide operation range, which can effectively protect against over-voltage and under-voltage operation. The on-time of the device is adjustable over a wide range, so the user can optimize the performance of the device. The device also has a low start-up and operating current, which can reduce overall system power losses.

The device also integrates an integrated EMI filter, which is designed to meet the requirements of global safety and industry regulations. The device has an integrated TVS (Transient Voltage Suppression) which can protect the device from high inrush current and surges. The device also features an internal start-up protection circuit which can reduce the possibility of EMI failures. The device uses an integrated reverse current protection function which can effectively protect against reverse current flow, ensuring safe operation of the device.

In addition, the FSCM0765RJX also provides short-circuit protection, over-temperature protection and overload protection to ensure the safe operation of the device. Moreover, this device supports an adjustable soft-start function, which reduces the inrush current and surges of the product, further protecting the system.

The FSCM0765RJX is an ideal solution for applications requiring an AC/DC and DC/DC offline switcher, providing high performance and competitive pricing. This device has a low start-up current, and integrates a variety of features such as reverse current protection, EMI filter, integrated TVS, and short-circuit protection. Taking into account both the performance and cost, the FSCM0765RJX is an ideal solution for a variety of AC/DC and DC/DC Power Supplies.
