ON Semiconductor FSL136MRS Green Mode Fairchild Power Switch (FPS™)

The ON Semiconductor FSL136MRS is a versatile and energy-efficient power switch designed for high-performance switch mode power supplies. With its integrated Pulse Width Modulation (PWM) controller and high-voltage power MOSFET, this device is an all-in-one solution that simplifies the design and enhances the reliability of power applications.

One of the key features of the FSL136MRS is its Green Mode function, which significantly reduces standby power consumption. When the load decreases, the FPS™ enters Green Mode, automatically reducing the switching frequency and minimizing power loss. This feature is particularly beneficial for meeting international energy-saving standards, making the FSL136MRS an environmentally friendly choice for power supply designs.

The device boasts a wide range of built-in protections to ensure the safety and durability of the end application. Overvoltage protection (OVP) guards the circuit against excessive voltage conditions, while overcurrent protection (OCP) prevents the power switch from damage due to current overloads. Additionally, the thermal shutdown (TSD) feature provides protection against overheating, enhancing the longevity of the power supply.

The FSL136MRS is designed with a high-voltage startup circuit that enables the power supply to start up under full-load conditions. This high-voltage capability also allows the device to withstand voltage spikes, further ensuring the robustness of the power supply.

With its Burst-Mode operation, the FSL136MRS offers excellent efficiency at light-load conditions, which is essential for applications that require low standby power consumption. The internal frequency jittering feature also helps in reducing EMI emission, simplifying the task of meeting EMI regulations.

Applications for the FSL136MRS include a wide variety of power supply systems, such as LCD monitors, TVs, DVD players, and other low-power consumer electronics that demand high efficiency and low standby power consumption. With its advanced features and green mode operation, the FSL136MRS is an ideal choice for designers looking to create compact, energy-efficient power solutions.
