Hot sale Original TNY177PN PMIC IC Isolated Converter Offline Flyback, Secondary Side SR Topology 132kHz 8-PDIP-C
Original TNY177PN PMIC IC Isolated Converter Offline Flyback, Secondary Side SR Topology 132kHz 8-PDIP-C 650V 23.5 W Through Hole
Product Description
TinySwitch-LTincorporates a 650 V power MOSFET, oscillator, high voltage switched current source, current limit (user selectable) and thermal shutdown circuitry. The IC family uses an ON/OFF control scheme and offers a designflexible solution with a low system cost and extended power capability.
Product Highlights
Lowest System Cost with Enhanced Flexibility
• 650 V rating optimized for non-active PFC applications
• 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-LT choice by swapping devices with no other circuit redesign
• Tight I2f 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 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
• Auto-restart delivers <3% of maximum power in short circuit and open loop fault conditions
• Output overvoltage shutdown with optional Zener
• 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
Product Applications
• Chargers/adapters for cell/cordless phones, PDAs, digital cameras,
MP3/portable audio, shavers, etc.
• DVD/PVR and other low power set top decoders
• Supplies for appliances, industrial systems, metering, etc.
