The TOP221P is a high-performance AC-DC power supply integrated circuit (IC) designed to provide cost-effective solutions for medium power applications up to 36 watts in a variety of configurations. The TOP221P is a low-cost, high-performance, high-efficiency integrated power conditioning and monitoring circuit suitable for AC to DC, DC to DC and switch mode power supply (SMPS) applications. It features excellent power efficiency, low noise and low ripple operation, and is a suitable alternative to bulky and expensive linear power supplies.

The TOP221P application field includes DC to DC converters, AC/DC power adapters, offline switchers and more. DC to DC converters use the TOP221P to convert a fixed DC voltage to a variable DC voltage. It is ideal for applications such as UPS systems, battery chargers, solar inverters and power supply applications. AC/DC power adapters use the TOP221P to convert AC input to DC output through rectification. This type of transformer is used for powering consumer electronics such as PC’s, routers, and more. Lastly, offline switchers use the TOP221P to convert AC line power to DC output of the desired voltage and current.

The TOP221P integrates an internal high-voltage MOSFET switch, dual gate driver and several other necessary protection elements into a single IC package. This IC is designed to offer excellent EMI performance, with minimized EMI filter components. It also features a highly efficient power conversion with high power factor correction and low-noise operation.

The TOP221P is designed to operate in the standard voltage range of 6V to 36V with an adjustable switch frequency up to 2MHz. It is capable of providing up to 36 watts of output power. This IC is available in a small SOT-223 package and is extremely cost-effective compared to bulkier, more expensive linear power supplies.

The TOP221P includes several protection functions such as an adjustable soft-start, over current protection, under-voltage protection, overvoltage protection, overload protection and overtemperature protection. The TOP221P also includes a variable-frequency operation for adjustable noise control and energy efficiency. The built-in circuit breaker and Hiccup mode are suitable for total system protection.

The TOP221P is a cost-effective solution for medium power applications up to 36W and is suitable for DC to DC converters, AC/DC power adapters, offline switchers and other applications. It provides reliable high-efficiency conversion and excellent EMI performance, while its small package and low operating noise make it an ideal choice for these applications.
