Description
The FSL206MR integrated Pulse Width Modulator
(PWM) and SenseFET is specifically designed for high-
performance offline Switch Mode Power Supplies
(SMPS) with minimal external components. This device
is
combine an avalanche-rugged SenseFET with a current
mode PWM control block.
The integrated PWM controller includes: 7.8V regulator
for no 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, and
fault-protection circuitry such as Overload Protection
(OLP), Over-Voltage Protection (OVP), Abnormal Over-
Current Protection (AOCP) and Line Under-Voltage
Protection (LUVP). During startup, the FSL206MR
offers good soft-start performance.
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 power loss of 150mW with no-bias
winding and 25mW with bias winding at no-load
condition when the input voltage is 265V
