PWM controller provides a small form factor solution for space-constrained consumer electronics
The FAN6863 minimizes standby power consumption by using a proprietary green-mode function that provides off-time modulation to continuously decrease the switching frequency under light-load conditions. Under zero-load conditions, the power supply enters burst-mode, which shuts off the PWM output. This technology allows the device to achieve excellent standby power: <100 mW at no-load conditions, which enables designers to meet international power consumption requirements.
The FAN6863, packaged in a small form factor SSOT-6, is ideal for space constrained designs while offering functionality normally found in devices in larger packages. The device provides large gate driving capability – 400 mA for up to 40 W applications, surge capability up to 7 KV for higher reliability, as well as an integrated internal frequency hopping function which helps reduce EMI emissions with minimal line filters.
Samples of the FAN6863 PWM controller are available now. The devices are priced at $00.36 in 1,000 quantity pieces.
