Product Range Selector (TinySwitch-4 Series)
See all from this product rangeProduct Overview
The TNY289PG is an energy-efficient offline Switcher with line compensated overload power. TinySwitch-4 combines a high-voltage power MOSFET switch with a power supply controller in one device. Unlike conventional PWM controllers, it uses a simple ON/OFF control to regulate the output voltage. The controller consists of an oscillator and enables circuit (sense and logic), current limit state machine, 5.85V regulator, BYPASS/MULTIFUNCTION pin undervoltage, overvoltage circuit and current limit selection circuitry, over-temperature protection, current limit circuit, leading edge blanking and a 725V power MOSFET. TinySwitch-4 incorporates additional circuitry for line undervoltage sense, auto-restart, adaptive switching cycle on-time extension and frequency jitter. The drain pin is the power MOSFET drain connection. It provides internal operating current for both start-up and steady-state operation.
- Line compensated overload power - No additional components
- Dramatically reduces max overload variation over universal input voltage range
- Simple ON/OFF control, no loop compensation needed
- Selectable current limit through BP/M capacitor value
- Higher current limit extends peak power/in open frame, maximum continuous power
- Allows optimum TinySwitch-4 choice by swapping devices with no other circuit redesign
- Maximizes MOSFET and magnetic 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
- Pin-out simplifies heat sinking to the PCB
- SOURCE pins are electrically quiet for low EMI
- Accurate hysteretic thermal shutdown protection with automatic recovery eliminates need for reset
- Output overvoltage shutdown with optional Zener
- Fast AC reset with optional UV external resistor
- 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
- Extended creepage between DRAIN and all other pins improves field reliability
- Easily meets all global energy efficiency regulations
- ON/OFF control provides constant efficiency down to very light loads
- No-load
30mW with bias winding, 150mW at 265VAC without bias winding - Auto-restart delivers
3% of maximum power in short-circuit and open loop fault conditions - ±5% Turn-ON UV threshold - Line voltage sense with single external resistor
- 725V Rated MOSFET - Increases BV de-rating margin
Applications
Power Management, Consumer Electronics, Industrial, Metering, Audio
