FSL4110LRN Description

Short technical summary and product information.

The FSL4110LRN from ON Semiconductor is an integrated pulse width modulation (PWM) controller and a 1000 V avalanche rugged SenseFET. It is specifically designed for high input voltage offline Switching Mode Power Supplies (SMPS) requiring minimal external components.

 

This device operates at a precise fixed frequency of 50 kHz and supports a power output of 9 W. It includes various protection functions such as Overload Protection (OLP), Over-Voltage Protection (OVP), Abnormal Over-Current Protection (AOCP), and Internal Thermal Shutdown (TSD) with hysteresis. The operating voltage range is 8V to 27V, with a duty cycle of 67%.

 

The FSL4110LRN is housed in a 7-DIP package and is designed for through-hole mounting. It offers features like soft burst-mode operation for minimizing audible noise and random frequency fluctuation for low EMI. Compared to discrete solutions, it reduces cost, component count, and PCB size while increasing efficiency and system reliability.

 

Applications include SMPS for electric metering and auxiliary power supplies for 3-phase input industrial systems.
