Products Detail

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. It offers lowest system cost with enhanced flexibility, enhanced safety and reliability features, and EcoSmart energy efficiency.

Key Features

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
Tight I2f parameter tolerance reduces system cost
Maximizes MOSFET and magnetics power delivery
ON time extension extends low line regulation range/hold-up time
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
Accurate hysteretic thermal shutdown with automatic recovery
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
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
