Product Description

The TNY290PG 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
