Output Power Table. Notes: 1. Minimum continuous power in a typical non-ventilated enclosed adapter measured at +50 °C ambient. Use of an external heat sink will increase power capability. 2. Minimum continuous power in an open frame design (see Key Applications Considerations). 3. Packages: P: DIP-8C, G: SMD-8C, D: SO-8C. Lead free only. See Part Ordering Information. 4. See Key Application Considerations. Product Highlights Lowest System Cost with Enhanced Flexibility • Simple ON/OFF control, no loop compensation needed • Unique Peak Mode feature extends power range without increasing transformer size • Maximum frequency and current limit boosted at peak loads • Selectable current limit through BP/M capacitor value • Higher current limit extends maximum power in open frame • Lower current limit improves efficiency in enclosed adapters • Allows optimum TinySwitch-PK choice by swapping devices with no other circuit redesign • Tight I2f parameter tolerance reduces system cost • Maximizes MOSFET and magnetics power delivery • ON time extension – typically extends low line regulation range/ hold-up time to reduce input bulk capacitance • Self-biased: no bias winding required for TNY375-376; winding required for TNY377-380 • Frequency jittering reduces EMI filter costs • Optimized pin out eases pcb/external heat sinking • Quiet source-connected heat sink pins for low EMI Enhanced Safety and Reliability Features • Accurate hysteretic thermal shutdown with automatic recovery provides complete system level overload protection and eliminates need for manual reset • Auto-restart delivers <3% maximum power in short circuit and open loop fault conditions • Output overvoltage shutdown with optional Zener • Line undervoltage detect threshold set using a single 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 <170 mW at 265 VAC without bias winding, <60 mW with bias winding • ON/OFF control provides constant efficiency down to very light loads – ideal for mandatory CEC efficiency regulations and 1 W PC standby requirements Applications • Applications with high peak-to-continuous power demands – DVDs, PVRs, active speakers (e.g. PC audio), audio amplifiers, modems, photo printers • Applications with high power demands at startup (large output capacitance or motor loads) – PC standby, low voltage motor drives Description TinySwitch-PK incorporates a 700 V MOSFET, oscillator, high- voltage switched current source, current limit (user selectable), and thermal shutdown circuitry. A unique peak mode feature boosts current limit and frequency for peak load conditions. The boosted current limit provides the peak output power while the increased peak mode frequency ensures the transformer can be sized for continuous load conditions rather than peak power demands.
