IR2159S Description

Short technical summary and product information.

The IR2159S from Infineon Technologies is a versatile dimming ballast controller and 600V half-bridge driver integrated into a single IC. It is designed for transformer-less lamp power sensing and regulation, simplifying the adaptation of non-dimming ballasts for dimming applications.

Key features include closed-loop lamp power control, closed-loop preheat current control, and programmable preheat time and current. It offers a 0.5 to 5VDC dimming control input, with adjustable minimum and maximum lamp power settings. The device also provides programmable minimum frequency operation.

For enhanced reliability, the IR2159S includes full lamp fault protection, brown-out protection, automatic restart, micro-power startup, and over-temperature protection. It operates within a voltage range of 12V to 16.5V with a typical current consumption of 10mA and a frequency range of 25kHz to 95kHz.

This IC is housed in a 16-lead SOIC package, suitable for surface mount applications. Its operating temperature range is -40°C to 125°C.
