The TOP223PN is an AC-DC converter, off-line switching regulator integrated circuit (IC) designed for use in universal-input, voltage-regulation applications from ICs to appliances. It features a cycle-by-cycle current limiting circuit, a high-side switch, a low-side switch, and a resetable foldback current limiting circuit. It is ideal for usage in a variety of electronic devices such as PC peripherals, LED driver, power adapter, street lighting, automotive ignition and various other home gadgets.
It offers an astonishing power efficiency of up to 80%, making it an attractive option for designers looking for energy-saving solutions for their projects. It also offers a wide input voltage range that allows it to be used with universal AC power supplies. The IC is rated up to 10W output power, making it suitable for use in low to medium power applications.
The principle behind the circuit is relatively simple. It utilizes a staircase voltage-controlled oscillator to periodically place the high-side switch into conduction and the low-side switch into regeneration, resulting in the transfer of energy from the input to the output of the device. This oscillator works in conjunction with a power switch with no dead-time control, which allows it to regulate output voltage according to changing input voltage levels.
It also features a cycle-by-cycle current limiting circuit that quickly limits output current in cases of any overcurrent conditions, helping to protect the components from any damage that may be caused. The foldback current limiting circuit helps to prevent overcurrent conditions from occuring in the first place. The preset output voltage and the current limiting circuitry can be further adjusted by adding external components.
The TOP223PN is designed to provide cost-effective solutions and unparalleled performance. With its wide input range, adjustable output voltage and cycling current limiting, the circuit offers an excellent combination of features that make it suitable for use in a variety of applications.
