The FSL126HR is an integrated Pulse Width Modulator (PWM) and SENSEFET designed for high-performance offline Switch-Mode Power Supplies (SMPS). It features an internal avalanche-rugged SENSEFET rated for 650 V and includes a variety of protective functions such as Under-Voltage Lockout (UVLO), Over Voltage Protection (OVP), and Thermal Shutdown (TSD). The device operates with a low standby power consumption of under 50 mW at 265 Vac in no-load conditions and has a built-in soft-start feature with a duration of 20 ms. The FSL126HR supports a maximum output power of 21 W under typical conditions and is suitable for applications including adapters and home appliances. It operates within a temperature range of -40¬8C to 105¬8C and has a fixed operating frequency of 100 kHz with frequency modulation to reduce electromagnetic interference (EMI). The package is an 8-lead Dual Inline Package (DIP), making it suitable for through-hole mounting. This product is positioned as a cost-effective solution for designing flyback converters, reducing component count and enhancing system reliability.
