Pulse Width Modulator (PWM) Controllers
Fairchild’s green-mode PWM controllers have a function to minimize the standby power consumption enabling power
supplies to meet international energy regulation requirements. The green-mode function provides off-time modulation,
which gradually decreases the switching frequency as the load drops under light load conditions. Under zero-load
conditions, the power supply enters burst mode.

fairchild power switch (fps™)
Fairchild’s FPS products cover a wide range of power supply applications—from small battery chargers to large
televisions, up to 250W. These highly integrated FPS devices combine the functionality of a fully avalanche-rugged
SenseFET, a current mode pulse width modulation (PWM) IC and various protection functions, to simplify design and
improve system reliability. Fairchild’s FPS products provide the highest levels of efficiency to meet the standards as
specified by international regulatory agencies.
Green FPS™
Fairchild’s Green FPS™ provides high energy efficiency and system reliability in DVD players, set-top
boxes, LCD monitors and other power supply designs below 25W. Based on Fairchild’s proprietary valley
switching technique, these Green FPS products increase power conversion efficiency by 1% and reduce EMI up
to 5dB, when compared to conventional hard-switching topologies. Utilizing an advanced burst mode operation,
the Green FPS e-Series devices meet standby power regulations by reducing standby power consumption to below
0.2W at no load conditions (below 1W at 0.5W load).
Features & Benefits
• Optimized for valley switching operation
- Frequency clamp in the valley switching mode allows
the efficiency levels to remain high at lighter load levels
• Pulse-by-pulse current limit
•
• High efficiency through minimum voltage switching
• 1% improvement over hard-switching topologies
Various protection functions: over load protection (OLP),
over voltage protection (OVP), abnormal over current protection (AOCP), internal thermal shutdown (TSD), output short protection (OSP)
• Low EMI through valley switching and inherent
frequency modulation
• Under voltage lock out (UVLO) with hysteresis
• Up to 5dB over hard-switching topologies
• Built-in soft-start (15ms)
• Internal startup circuit
• Advanced burst-mode operation for low standby
power consumption and minimized audible noise
• Minimum component counts on primary side
• Narrow frequency variation range over wide load
and input voltage variation AC

integrated power solutions
Fairchild’s integrated MOSFET module family enables higher conversion efficiency while significantly reducing board
space in synchronous Buck designs. Each module in the FDMS96xx series combines a carefully selected high side
and low side N-Channel MOSFET and one monolithically integrated Schottky diode into a single, space-efficient,
5mm x 6mm MLP package. The pin-out design of the FDMS96xx series is optimized for direct and easy connection
in PCB layouts to standard driver ICs. This innovative package concept shortens design time and reduces parasitic
inductances in board layout traces, improving overall system efficiency.

IGBTs
Fairchild’s IGBTs are optimized for Switch Mode Power Supply designs offering better VSAT and EOFF. Additionally, this
control smoothes the switching waveforms for less EMI. IGBTs are manufactured using an optimized design process
which offers better control and repeatability of the top side structure, thereby providing tighter specifications.
IGBTs vs. MOSFETs
Reduce System Cost
• Reduce conduction losses due to low saturation voltage
• Smaller die size for higher voltages reduces overall costs
• Reduce current tail, reduce switching losses
• May eliminate components
• Improve transistor and system reliability
• Increase operating frequency and reduce transformer/filter costs
• IGBTs superior in current density facilitate higher output power
• Fastest switching IGBTs in the market today

optocouplers
Snubberless TRIAC Drive Optocouplers
The optocouplers feature a built-in active dv/dt clamp providing best-in-class noise immunity (dv/dt) of 10,000V/μs,
which is superior to the average dv/dt rating (1,500V/μs) of monolithic TRIAC drivers. This superior performance
eliminates the RC snubber network required for lower dv/dt-rated monolithic opto TRIAC drivers.
Features
• Integrated zero-cross inhibit circuit prevents switching near
the peak of the AC mains

design easier, simpler, and more cost effective. The example below shows an industrial application requiring 70W
output. No heatsink is needed.
• No heatsink needed for power levels up to 200W
• Less than 1.8W input standby power
– Excellent for a resonant converter
– Achieved using power save mode of operation
• Full load efficiency better than 90%
– Good efficiency for a 70W power supply
– For 200W power supplies this is more

200W LLC RESONANT HALF-BRIDGE CONVERTER
200W LLC Resonant Half-Bridge Converter Using the FAN7621
(340-400VDC to 24VDC)
Typical Applications: Telecom power supplies, LCD TVs, servers
The LLC resonant topology is characterized by softly commutated switches as well as the power being processed in a
sinusoidal manner. These characteristics allow for reduced switching loss, and therefore higher efficiency, as well as a
reduction in the EMI signature. The FAN7621 evaluation board illustrates these characteristics in a 200W converter.
The FAN7621 controller allows the designer to optimize the FET selection for the particular application.
• 95% Efficiency and 30ms holdup at 390VDC in full load
• <350mV PP ripple
• All components <70°C at full load with natural convection

The FAN6982 includes circuits for the implementation of leading edge, average current, “boost”-type power factor
correction. A TriFault Detect™ function helps reduce external componets and provides full protection for feedback
loops such as open, short, and over voltage. The over-voltage comparator shuts down the PFC stage in the event of a
sudden load decrease.

DDR3 Memory Power Supply
Typical Applications: Notebooks, servers, set-top boxes, general high performance/low power applications
This small form factor solution provides the three main supplies (VDDQ, VTT, VREF ) for DDR1, DDR2, or DDR3 applications.
By simple component changes, this solution can support down to 1.5V VDDQ and 0.75V VTT. The FAN5236 controller
with external dual MOSFETs can deliver up to 14A, and by changing the selected MOSFETs, higher currents can be
achieved. The three main ICs (controller + 2 dual FETs with integrated Schottky diodes) reduce component count and
increase efficiency.
• Wide input voltage range: 5V to 24V
• Very low 1µA shutdown
• Typical DDR3 requirements: 1.5V, 0.5A and 0.75V,
2A output supplies
• > 94% overall system efficiency
