DESCRIPTION

· TinySwitch-III integrates a 700 V power MOSFET, oscillator, high-voltage switched current source, user-selectable current limit, and thermal shutdown circuitry.

· Utilizes an ON/OFF control scheme for simplified design and low system cost.

· Offers extended power capability and design flexibility.

FEATURES

· Simplifies system design with no loop compensation required.

· Selectable current limit via BP/M capacitor value for optimized performance.

· Tight I2f parameter tolerance reduces system costs.

· ON-time extension enhances low line regulation and reduces input bulk capacitance.

· Self-biased design eliminates the need for bias winding or components.

· Frequency jittering minimizes EMI filter costs.

· Enhanced safety with accurate hysteretic thermal shutdown and auto-restart features.

· EcoSmart™ technology ensures compliance with global energy efficiency standards.

APPLICATIONS

· Chargers and adapters for mobile devices, portable audio, and personal care appliances.

· PC standby and auxiliary power supplies.

· Low power set-top boxes and decoders for DVD/PVR systems.

· Power supplies for appliances, industrial systems, and metering equipment.
