The product is the TOPSwitch-GX series switch power supply, with an input voltage range of 85-265 VAC and a maximum output power of 290 W. The product has the characteristics of low system cost, high design flexibility, external programmable accurate current limit, wider duty cycle and so on.
This document describes the TOPSwitch-GX family of integrated offline switchers from Integrations, Inc., specifically the TOP242-250 series. These devices integrate the high voltage power MOSFET, PWM control, and fault protection circuitry onto a single CMOS chip to reduce system cost and improve design flexibility. The family supports an extended power range up to 290W and includes features such as externally programmable current limits, line sensing, and frequency jittering for reduced EMI.
| Extended Power Range | up to 290 W |
|---|---|
| Switching Frequency | 132 kHz |
| Remote Off Mode Consumption | 80 mW @ 110 VAC |
| Remote Off Mode Consumption | 160 mW @ 230 VAC |
The extended power range goes up to 290 W.
It uses frequency jittering to reduce EMI and EMI filtering costs.
