FSL206MR
Green Mode Power Switch
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
components. This device integrates high−voltage power regulators
that combine 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−compensated precision
current sources for loop compensation; 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 mW with no bias winding and 25 mW (for FSL206MR) or
30 mW (for FSL206MRBN) with a bias winding under no−load
conditions when the input voltage is 265 Vac.
Features
• Internal Avalanche−Rugged SENSEFET 650 V
• Precision Fixed Operating Frequency: 67 kHz
• No−Load < 150 mW at 265 Vac without Bias Winding; <25 mW with
Bias Winding for FSL206MR, < 30 mW with Bias Winding for
FSL206MRBN
• No Need for Auxiliary Bias Winding
• Frequency Modulation for Attenuating EMI
• Line Under−Voltage Protection (LUVP)
• Pulse−by−Pulse Current Limiting
• Low Under−Voltage Lockout (UVLO)
• Ultra−Low Operating Current: 300 mA
• Built−In Soft−Start and Startup Circuit
• Various Protections: Overload Protection (OLP), Over−Voltage
Protection (OVP), Thermal Shutdown (TSD), Abnormal
Over−Current Protection (AOCP) Auto−Restart Mode for All
Protections
