FSL126MR Description

Short technical summary and product information.

The FSL126MR from ON Semiconductor is an integrated Green-Mode Power Switch designed for efficient offline Switch-Mode Power Supplies (SMPS). It combines a Pulse Width Modulator (PWM) controller with an avalanche-rugged SENSEFET, minimizing external components.

 

Key electrical features include a 650V internal SENSEFET, a typical operating current of 1.8 mA, and a soft-start time of 15 ms. The device operates with a precision fixed frequency of 67 kHz, incorporating frequency modulation for EMI attenuation. It offers various protection mechanisms such as Over-Voltage Protection (OVP), Overload Protection (OLP), Output-Short Protection (OSP), Abnormal Over-Current Protection (AOCP), and Thermal Shutdown (TSD).

 

This power switch supports maximum output power up to 21W in an open frame configuration at 230VAC. It is suitable for cost-effective flyback converter designs. The device is housed in an 8-DIP package and is designed for through-hole mounting.

 

Applications include SMPS for VCR, STB, DVD, DVCD players, home appliances, and adapters. The FSL126MR reduces component count, design size, and weight while increasing efficiency and system reliability.
