FSDM0365RNB
SMPS Power Switch, Built-in Soft Start improved (Green)
Features Internal Avalanche Rugged Sense FET Consumes only 0.65W at 240VAC & 0.3W load with
Advanced Burst-Mode Operation Frequency Modulation for low EMI Precision Fixed Operating Frequency Internal Start-up Circuit Pulse by Pulse Current Limiting Over Voltage Protection Over Load Protection Internal Thermal Shutdown Function Auto-Restart Mode Under V oltage Lockout Low Operating Current (3mA) Adjustable Peak Current Limit Built-in Soft Start
Applications SMPS for VCR, SVR, STB, DVD & DVCD SMPS for Printer, Facsimile & Scanner Adaptor for Camcorder
DescriptionThe FSDx0365RNB(x stands for L, M) are integrated Pulse
Width Modulators (PWM) and Sense FETs specifically
designed for high performance offline Switch Mode Power
Supplies (SMPS) with minimal external components. Both
devices are integrated high voltage power switching regula-
tors which combine an avalanche rugged Sense FET with a
current mode PWM control block. The integrated PWM con-
troller features include: a fixed oscillator with frequency
modulation for reduced EMI, Under Voltage Lock Out
(UVLO) protection, Leading Edge Blanking (LEB), opti-
mized gate turn-on/turn-off driver, Thermal Shut Down
(TSD) protection and temperature compensated precision
current sources for loop compensation and fault protection
circuitry. The FSDx0365RNB offer better performance in
Soft Start than FSDx0365RN. When compared to a discrete
MOSFET and controller or RCC switching converter solu-
tion, the FSDx0365RNB reduce total component count,
design size, weight and at the same time increase efficiency,
productivity, and system reliability. Both devices are a basic
platform well suited for cost effective designs of flyback
converters.
