Description
The TNY175PN IC is designed to provide high-voltage power conversion in a compact package. It combines a high-voltage power MOSFET, control circuitry, and protection features into a single chip, making it suitable for designing compact and efficient power supplies.
Key features and specifications:
(1) Power Output: The TNY175PN is capable of delivering output power up to 15 watts, depending on the design and application.
(2) Primary-Side Control: It utilizes primary-side control, where the control circuitry is powered from the primary side of the transformer. This eliminates the need for an optocoupler, reducing the component count and cost.
(3) Energy Efficient: The IC incorporates advanced control techniques and operates in a frequency modulation mode, optimizing efficiency and reducing power consumption.
(4) Protections: The TNY175PN offers several built-in protection features such as auto-restart for fault conditions, over-temperature protection, over-voltage protection, and short-circuit protection.
TinySwitch-LT incorporates a 650 V power MOSFET, oscillator, high voltage switched current source, current limit (user selectable) and thermal shutdown circuitry. The IC family uses an ON/OFF control scheme and offers a design fl exible solution with a low system cost and extended power capability.
Enhanced Safety and Reliability Features
• Output overvoltage shutdown with optional Zener
• Very low component count enhances reliability and enables single-sided printed circuit board layout
• High bandwidth provides fast turn on with no overshoot and excellent transient load response
