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 efficiency 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 and 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 filter costs
• Pin-out simplifies 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 field reliability
EcoSmart™– Extremely Energy Efficient
• Easily meets all global energy efficiency regulations
• No-load <150 mW at 265 VAC without bias winding, <50 mW with bias winding
• ON/OFF control provides constant efficiency down to very light loads – ideal for mandatory CEC regulations and 1 W PC standby requirements
Applications
• Chargers/adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio, shavers, etc.
• PC Standby and other auxiliary supplies
• DVD/PVR and other low power set top decoders
• Supplies for appliances, industrial systems, metering, etc.
