TOPSwitch^®-GX Family

Extended Power, Design Flexible,

EcoSmart,^®IntegratedOff-line Switcher

Product Highlights

Lower System Cost, High Design Flexibility

OUT

• Extended power range to 290 W

• Features eliminate or reduce cost of external components

• Fully integrated soft-start for minimum stress/overshoot

• Externally programmable accurate current limit

• Wider duty cycle for more power, smaller input capacitor

CONTROL

• Separate line sense and current limit pins on Y/R/F packages

• Line under-voltage (UV) detection: no turn off glitches

• Line overvoltage (OV) shutdown extends line surge limit

TOPSwitch-GX

• Line feed forward with maximum duty cycle (DC_MAX

reduction rejects line ripple and limits DC_MAXat high line

• Frequency jittering reduces EMI and EMI filtering costs

• Regulates to zero load without dummy loading

)

PI-2632-060200

Figure 1. Typical Flyback Application.

• 132 kHz frequency reduces transformer/power supply size

• HalffrequencyoptioninY/R/Fpackagesforvideoapplications

• Hysteretic thermal shutdown for automatic fault recovery

• Large thermal hysteresis prevents PC board overheating

TOPSwitch-GX uses the same proven topology as TOPSwitch,

cost effectively integrating the high voltage power MOSFET,

PWM control, fault protection and other control circuitry onto a

single CMOS chip. Many new functions are integrated to re-

duce system cost and improve design flexibility, performance

and energy efficiency.

Depending on package type, the TOPSwitch-GX family has

either 1 or 3 additional pins over the standard DRAIN, SOURCE

and CONTROL terminals allowing the following functions: line

sensing (OV/UV, line feedforward/DC max reduction), accu-

rate externally set current limit, remote on/off, and synchroni-

zation to an external lower frequency and frequency selection

(132 kHz/66 kHz).

All package types provide the following transparent features:

Soft-start, 132 kHz switching frequency (automatically reduced

at light load), frequency jittering for lower EMI, wider DC_MAX

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 at 50 °C ambient. See

Key Applications for detailed conditions. 3. See Part Ordering

Information. 4. 230 VAC or 100/115 VAC with doubler.

hysteretic thermal shutdown and larger creepage packages. In

addition, all critical parameters (i.e. current limit, frequency,

PWM gain) have tighter temperature and absolute tolerance, to

simplify design and optimize system cost.
