FSQ0365RLX Description

Short technical summary and product information.

The FSQ0365RLX is an integrated Pulse-Width Modulation (PWM) controller and SENSEFET from ON Semiconductor, optimized for valley switching converter designs. This device offers low EMI through variable frequency control and high efficiency via minimum voltage switching. It operates with an input voltage range of 8V to 20V and a frequency between 55kHz and 67kHz, delivering up to 25W of power.

 

Key features include pulse-by-pulse current limit and protection functions such as Overload Protection (OLP), Over-Voltage Protection (OVP), Abnormal Over-Current Protection (AOCP), and Internal Thermal Shutdown (TSD). The integrated 650V SENSEFET and a built-in soft-start function of 15ms simplify external component requirements.

 

This component is housed in an 8-LSOP Surface Mount package, suitable for various power supply applications including adapters and auxiliary power supplies for consumer electronics. The operating temperature range is -40°C to 85°C (TA).
