1.1. General Description
This user guide supports the evaluation kit for the FSL206MR. It should be used in
conjunction with the FSL206MR datasheet as well as Fairchild’s application notes and
technical support team. Please visit Fairchild’s website at www.fairchildsemi.com.
This document is an engineering report describing measured performance of the
FSL206MR.
The FSL206MR integrated Pulse Width Modulator (PWM) and SenseFET is specifically
designed for high-performance offline Switched-Mode Power Supplies (SMPS) with
minimal external components. This device is an integrated high-voltage power regulator
that combines 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. Protections include 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
