Infineon Technologies ICE3AR2280VJZ | Demoboard AN-EVAL ICE3AR2280VJZ

Description

The EVAL ICE3AR2280VJZ evaluation board is a low cost off-line flyback switch mode power supply (SMPS) using the ICE3AR2280VJZ integrated power IC from the CoolSET™-F3R80 family. The circuit shown in Figure 2 details a 5 V, 20 W power supply that operates from an AC line input voltage range of 85 VAC to 265 VAC and line input OVP detect/reset voltage is 300/282 VAC, suitable for applications in enclosed adapter or openframe auxiliary power supply for different system such as white goods, PC, server, DVD, LED TV, Set-top box, etc.

Features

• 800 V avalanche rugged CoolSET™ with startup cell
• Active Burst Mode for lowest standby power
• Selectable entry and exit burst mode level
• 100kHz internally fixed switching frequency with jittering feature
• Auto restart protection for over load, open Loop, VCC under voltage and over voltage and overn temperature
• Over temperature protection with 50 °C hysteresis
• Built-in 10 ms soft start
• Built-in 20 ms and extendable blanking time for short duration peak power
• Propagation delay compensation for both maximum load and burst mode
• Adjustable input OVP
• Overall tolerance of current limiting < ±5%
• BiCMOS technology for low power consumption and wide VCC voltage range
• Soft gate drive with 50 Ω turn-on resistor

Typical applications

• Enclosed adapter or open frame auxiliary power supply of white goods, PC, server, DVD, TV, Set-top box, etc
