Lower System Cost, High Design Flexibility
Features eliminate or reduce cost of external components
Fully integrated soft-start for minimum stress/overshoot
Externally settable accurate current limit
Wider duty cycle for more power, smaller input capacitor
Line under-voltage (UV) detection: no turn off glitches
Line overvoltage (OV) shutdown extends line surge limit
Line feed forward with maximum duty cycle (DC
)
reduction rejects ripple and limits DC
at high line
Single resistor sets OV/UV thresholds, DC
reduction
Frequency jittering reduces EMI and EMI filtering costs
Regulates to zero load without dummy loading
132 kHz frequency reduces transformer/power supply size
Half frequency option for video applications
Hysteretic thermal shutdown for automatic recovery
Large thermal hysteresis prevents PC board overheating
Standard packages with omitted pins for large creepage
Active-on and active-off remote ON/OFF capability
Synchronizable to a lower frequency

Energy Efficient
Cycle skipping reduces no-load consumption
Reduced consumption in remote off mode
Half frequency option for high efficiency standby
Allows shutdown/wake-up via LAN/input port
Description
TOPSwitch-FX
uses the proven
TOPSwitch
topology and cost
effectively integrates many new functions that reduce system
cost and, at the same time, improve design flexibility,
performance and energy efficiency. Like
TOPSwitch
, the high
voltage power MOSFET, PWM control, fault protection and
other control circuitry are all integrated onto a single CMOS
chip, but with two added terminals. The first one is a MULTI-
FUNCTION (M) pin, which implements programmable line
OV/UV shutdown and line feed forward/DC
reduction with
line voltage. The same pin can be used instead to externally set
an accurate current limit. In either case, this pin can also be used
for remote ON/OFF or to synchronize the oscillator to an
external, lower frequency signal. The second added terminal is
the FREQUENCY (F) pin and is available only in the Y
package. This pin provides the half frequency option when
connected to CONTROL (C) instead of SOURCE (S). The
features on the new pins can be disabled by shorting them to the
SOURCE, which allows the device to operate in a three terminal
TOPSwitch
mode, but with the following new transparent
features: soft-start, cycle skipping, 132 kHz switching frequency,
frequency jittering, wider DC
, hysteretic thermal shutdown
and larger creepage. In addition, all critical parameters such as
frequency, current limit, PWM gain, etc. have tighter temperature
and absolute tolerances compared to the
TOPSwitch-II
family.
Higher current limit accuracy and larger DC
, when combined
with other features allow for a 10% to 15% higher power
capability on the
TOPSwitch-FX
devices compared to equivalent
TOPSwitch-II
devices for the same input/output conditions.
