Overview

TinySwitch-III incorporates a 700 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 design flexible solution with a low system cost and extended power capability.

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.

Key features

Minimum system cost with enhanced flexibility:
Simple ON/OFF control — no loop compensation required
Selectable current limit via BP/M capacitor value
Higher current limit for extended peak power or maximum continuous power in open-frame applications
Lower current limit for improved efficiency in enclosed adapter/charger applications
Optimal TinySwitch-III selection via device substitution — no redesign of surrounding circuitry required
Tight I parameter tolerance for reduced system cost
Maximized power delivery through MOSFET and magnetic components
Minimized maximum overload power, reducing transformer, primary clamp, and secondary component costs
Extended on-time — widened low-line regulation range/hold-up time to reduce input bulk capacitance
Self-biased: no bias winding or bias components required
Frequency jitter for reduced EMI filter cost
Pin layout simplifies PCB thermal management
Electrically quiet source pin for reduced EMI
Enhanced safety and reliability features:
Accurate hysteretic thermal shutdown with auto-recovery — no manual reset required
Improved auto-restart providing <3% maximum power under short-circuit and open-loop fault conditions
Output overvoltage shutdown with optional Zener diode
Line undervoltage detection threshold settable via single optional resistor
Ultra-low component count for enhanced reliability and single-sided PCB layout support
High bandwidth for fast turn-on with no overshoot and excellent transient load response
Extended creepage distance between drain and all other pins for improved field reliability
EcoSmart — Extremely High Energy Efficiency:
Easily meets all global energy efficiency regulations
No-load consumption <150mW at 265 VAC without bias winding; <50mW with bias winding
ON/OFF control delivers constant efficiency at light load — ideal for mandatory CEC regulations and 1 W PC standby requirements
