TNY290PN AC/DC Switching Converter IC
TNY290PN IC - Power Integrations AC/DC Converter
TNY290 is TinySwitch-4 Family Energy-Efficient, Off-Line Switcher with Enhanced Flexibility and Extended Power Range. TNY290PN Switching Converter IC incorporates a 725 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 flexible solution with a low system cost and extended power capability.
TNY290PN AC/DC Switching Converter IC combines a high-voltage power MOSFET switch with a power supply controller in one device. Unlike conventional PWM (pulse width modulator) controllers, it uses a simple ON/OFF control to regulate the output voltage. The controller consists of an oscillator, enable circuit (sense and logic),current limit state machine, 5.85 V regulator, BYPASS/MULTIFUNCTION pin undervoltage, overvoltage circuit, and current limit selection circuitry, over-temperature protection, current limit circuit, leading edge blanking, and a 725 V power MOSFET. TinySwitch-4 incorporates additional circuitry for line undervoltage sense,auto-restart, adaptive switching cycle on-time extension, and frequency jitter.

Features of TNY290PN AC/DC Converter IC
- 725 V rated MOSFET Increases BV de-rating margin
- Line compensated overload power – no additional components
- Dramatically reduces max overload variation over universal input voltage range
- ±5% turn on UV threshold: line voltage sense with single external resistor
- Simple ON/OFF control, no loop compensation needed
- Selectable current limit through BP/M capacitor value
- Higher current limit extends peak power or, in open frame applications, maximum continuous power
- Lower current limit improves efficiency in enclosed adapters/chargers
- Allows optimum TinySwitch™-4 choice by swapping devices with no other circuit redesign
- Tight I2f parameter tolerance reduces system cost
- Maximizes MOSFET and magnetics utilization
- ON-time extension – extends low-line regulation range/hold-up time to reduce input bulk capacitance
- Self-biased: no bias winding or bias components
- Frequency jittering reduces EMI filter costs
- Pin-out simplifies heat sinking to the PCB
- SOURCE pins are electrically quiet for low EMI
Applications of TNY290PN AC/DC Converter IC
- PC Standby and other auxiliary supplies
- DVD/PVR and other low power set top decoders
- Supplies for appliances, industrial systems, metering, etc
- Chargers/adapters for cell/cordless phones, PDAs, digital cameras,MP3/portable audio, shavers, etc.
