TOPSwitch-FXFamily

Design Flexible, EcoSmart, Integrated

Off-Line Switcher

Product Highlights

Lower System Cost, High Design Flexibility

OUT

• 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

CONTROL

• Line feed-forward with maximum duty cycle (DC_MAX

reduction rejects ripple and limits DC_MAXat high line

)

TOPSwitch-FX

• Single resistor sets OV/UV thresholds, DC_MAXreduction

• 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

PI-2503-062515

Figure 1. Typical Flyback Application.

• 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

Description

9 W

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_MAXreduction

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

Notes:

1. Typical continuous power in a non-ventilated enclosed adapter measured at

50 ˚C ambient.

2. Maximum practical continuous power in an open frame design with adequate

heat sinking, measured at 50 ˚C ambient. See key applications section for

detailed conditions.

3. Packages: P: DIP-8B, G: SMD-8B, Y: TO-220-7B.

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_MAX, 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.
