TEA1533AT - NXP

TEA1533AT GreenChipTMII SMPS control IC

is the second generation of green The Switched Mode Power Supply (SMPS) control ICs operating directly from the rectified universal mains. A high level of integration leads to a cost effective power supply with a very low number of external components. The special built-in green functions allow the efficiency to be optimum at all power levels. This holds for.

Features

Distinctive features
• Universal mains supply operation (70 to 276 V AC)
• High level of integration, giving a very low external component count. Green features
• Valley or zero voltage switching for minimum switching losses
• Efficient quasi-resonant operation at high power levels
• Frequency reduction at low power standby for improved system efficiency (<3 W)
• Cycle skipping mode at very low loads; Pi <300 mW at no-load operation for a typical adapter application
• On-chip start-up current source. Protection features
• Safe restart mode for system fault conditions
• Continuous mode protecti.
