The FSL126HR from ON Semiconductor is an integrated Pulse Width Modulator (PWM) and SENSEFET designed for high-performance offline Switch-Mode Power Supplies (SMPS). This device integrates a high-voltage power switching regulator with an avalanche-rugged SENSEFET and a current-mode PWM control block.
Key features include a 650V internal avalanche-rugged SENSEFET, under 50 mW standby power consumption at 265 Vac no-load conditions with Burst Mode, and a precision fixed operating frequency with frequency modulation for attenuating EMI. It also offers built-in soft-start of 20 ms, pulse-by-pulse current limit, and various protection features such as Over Voltage Protection (OVP), Overload Protection (OLP), Output-Short Protection (OSP), Abnormal Over-Current Protection (AOCP), and Internal Thermal Shutdown Function (TSD).
The FSL126HR is suitable for cost-effective flyback converter designs. It operates with a voltage range of 8V to 26V and a typical operating temperature range of -40°C to 105°C. The device comes in an 8-DIP package suitable for through-hole mounting.
Applications include SMPS for VCR, STB, DVD players, home appliances, and adapters. The device provides a basic platform that reduces total component count, design size, and weight while increasing efficiency, productivity, and system reliability compared to discrete solutions.
