Product Highlights
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
Enhanced Safety and Reliability Features
- Accurate hysteretic thermal shutdown protection with automatic recovery eliminates need for manual reset
- Auto-restart delivers <3% of maximum power in short-circuit and open loop fault conditions
- 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
EcoSmart™- Extremely Energy Efficient
- Easily meets all global energy efficiency regulations
- No-load <30 mW with bias winding, <150 mW at 265 VAC without bias winding
- ON/OFF control provides constant efficiency down to very light loads - ideal for mandatory CEC regulations and EuP standby requirements
Applications
- PC Standby and other auxiliary supplies
- DVD/PVR and other low power set top decoders
- Supplies for appliances, industrial systems, metering, etc
- Chargers/adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio, shavers, etc.
