FSL206MR Datasheet | onsemi

Description The FSL206MR integrated Pulse- Width Modulator (PWM) and SENSEFET® is specifically designed for high- performance offline Switched- Mode Power Supplies (SMPS) while minimizing external ponents. This device integrates high- voltage power regulators that bine an avalanche- rugged SENSEFET with a Current- Mode PWM control block. The integrated PWM controller includes: a 7.8 V regulator, eliminating the need for auxilliary bias winding; Under- Voltage Lockout (UVLO) protection; Leading- Edge Blanking (LEB); an optimized gate turn- on/turn- off driver; EMI attenuator; Thermal Shutdown (TSD) protection; temperature- pensated precision current sources for loop pensation; soft- start during startup; and fault- protection circuitry such as Overload Protection (OLP), Over- Voltage Protection (OVP), Abnormal Over- Current Protection (AOCP), and Line Under- Voltage Protection (LUVP). The internal high- voltage startup switch and the Burst- Mode operation with very low operating current reduce the power loss in Standby Mode. As a result, it is possible to reach a power loss of 150 m W with no bias winding and 25 m W (for FSL206MR) or 30 m W (for FSL206MRBN) with a bias winding under no- load conditions when the input voltage is 265 Vac.
