TNY284KG-TL

AC to DC Switching Converter Off-Line Switcher 124kHz to 140kHz T/R 11Pin SOP-B EP

* Output Power - Adapter : 6 W * Output Power - Open Frame : 11 W * Lowest System Cost with Enhanced Flexibility * 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
