ای سی تغذیه 20 وات،آفلاین سوئیچر Energy-Effi cient, Off-Line Switcher With Enhanced Flexibility and Extended Power Range
Product Highlights
Lowest System Cost with Enhanced Flexibility
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 effi ciency in enclosed adapters/chargers
Allows optimum TinySwitch-III choice by swapping devices with no other circuit redesign
Tight I2 f parameter tolerance reduces system cost
Maximizes MOSFET and magnetics power delivery
Minimizes max overload power, reducing cost of transformer, primary clamp & secondary components
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 fi lter costs
Pin-out simplifi es heatsinking to the PCB
SOURCE pins are electrically quiet for low EMI
Enhanced Safety and Reliability Features
Accurate hysteretic thermal shutdown protection with automatic recovery eliminates need for manual reset
Improved auto-restart delivers 3% of maximum power in short circuit and open loop fault conditions
Output overvoltage shutdown with optional Zener
Line undervoltage detect threshold set using a single optional 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 fi eld reliability
EcoSmart® – Extremely Energy Effi cient
Easily meets all global energy effi ciency regulations
No-load 150 mW at 265 VAC without bias winding 50 mW with bias winding
ON/OFF control provides constant effi ciency down to very light loads – ideal for mandatory CEC regulations and 1 W PC
standby requirements
