With over six billion units sold worldwide, TinySwitch integrated circuits are widely used in auxiliary and bias power supplies in industrial, medical, computer, and appliance applications. Designers have long appreciated TinySwitch products for their design simplicity and high efficiency, especially with light loads. TinySwitch integrated circuits were the first to incorporate Power Integrations' award-winning EcoSmart™ technology, which has saved approximately 200 terawatt-hours of electricity since 1998 by dramatically reducing standby power waste.
The TinySwitch-5 switching ICs feature an advanced control engine that precisely manages the switching frequency and power delivery to maximize efficiency, even under light loads. This allows the power supplies to easily meet the 300 mW light load power consumption limit set by the European Commission's Energy-related Products (ErP) Directive 2009/125/EC, while still delivering up to 220 mW of output power for display, control, and communication functions. An enhanced thermal package means the TinySwitch-5 ICs can deliver up to 75 W without a heatsink, and surge and sag protection ensures robustness for use in countries with unstable power grids.
Silvestro Fimiani, product marketing manager at Power Integrations, states: “TinySwitch has become the gold standard for small power supplies due to its efficiency and ease of use. With TinySwitch-5, designers can scale up to 175 W at full power, while easily achieving 220 mW output and meeting the needs of appliance manufacturers subject to the 300 mW standby power standard mandated by the European Union.”
Availability and Resources:
The price of the TinySwitch-5 starts at $0.35 for quantities of 10,000 units. Reference designs are available that describe: a 12W single-output power supply (DER-1017); a 26.5W dual-output power supply with excellent standby efficiency (RDR-1016); a 36W single-output power supply with high efficiency at light load (DER-1040); and a 120W power supply with 92 percent efficiency at 230V AC (DER-1027).
