TNY288PG switching power supply chip

Description: The TNY288PG is a highly integrated switching power supply IC designed for low-power applications. It is part of the TinySwitch-III family, which combines a high-voltage power MOSFET, oscillator, high-voltage switched current source, current limit, and thermal shutdown circuitry into a single monolithic IC. This integration significantly reduces the number of external components required, simplifying the design of compact, efficient, and reliable power supplies. Key Features:

• Integrates high-voltage power MOSFET, PWM controller, and startup circuitry
• On/Off control mode for high efficiency at light loads
• Wide input voltage range: 85V to 265V AC
• Frequency jittering for low EMI
• Adjustable current limit
• Built-in auto-restart for output overload protection
• Hysteretic thermal shutdown for over-temperature protection
• No-load consumption < 30mW at 265V AC
• Low component count
