TOPSwitch-FX Family

Design Flexible, EcoSmart^®, Integrated

Off-line Switcher

Product Highlights

Lower System Cost, High Design Flexibility

• Features eliminate or reduce cost of external components

OUT

• 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

TOPSwitch-FX

• Line feed forward with maximum duty cycle (DC_MAX

)

reduction rejects ripple and limits DC_MAXat high line

• 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

OUTPUT POWER TABLE

• 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

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

anaccuratecurrentlimit. Ineithercase,thispincanalsobeused

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,whichallowsthedevicetooperateinathreeterminal

Table 1. 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.

TOPSwitch mode, but with the following new transparent

features:soft-start,cycleskipping,132 kHzswitchingfrequency,

frequency jittering, wider DC_MAX, hysteretic thermal shutdown

and larger creepage. In addition, all critical parameters such as

frequency,currentlimit,PWMgain,etc.havetightertemperature

and absolute tolerances compared to the TOPSwitch-II family.

HighercurrentlimitaccuracyandlargerDC_MAX,whencombined

with other features allow for a 10% to 15% higher power

capabilityontheTOPSwitch-FXdevicescomparedtoequivalent

TOPSwitch-II devices for the same input/output conditions.
