Description
Each product in the FSD2x0B (x for 0, 1) family consists of
an integrated Pulse Width Modulator (PWM) and Sense
FET, and is specifically designed for high performance off-
line Switch Mode Power Supplies (SMPS) with minimal
external components. Both devices are integrated high volt-
age power switching regulators which combine an avalanche
rugged Sense FET with a current mode PWM control block.
The integrated PWM controller features include: a fixed
oscillator with frequency modulation for reduced EMI,
Under Voltage Lock Out (UVLO) protection, Leading Edge
Blanking (LEB), an optimized gate turn-on/turn-off driver,
Thermal Shut Down (TSD) protection and temperature com-
pensated precision current sources for loop compensation
and fault protection circuitry. When compared to a discrete
MOSFET and controller or RCC switching converter solu-
tion, the FSD2x0B devices reduce total component count,
design size, weight while increasing efficiency, productivity,
and system reliability. Both devices provide a basic platform
that is well suited for the design of cost-effective flyback
converters.
Notes:
1. Typical continuous power in a non-ventilated enclosed
adapter with sufficient drain pattern as a heat sinker, at
50
°C ambient.
2. Maximum practical continuous power in an open frame
design with sufficient drain pattern as a heat sinker, at 50
°C
ambient.
3. 230 VAC or 100/115 VAC with doubler.
