TPS61199 Description

Short technical summary and product information.

The TPS61199 from Texas Instruments is a highly integrated white LED driver solution for large-size LCD backlighting. This device integrates a current-mode boost controller and eight current sinks, enabling it to drive up to eight LED strings in parallel. Each string features an independent current regulator with a high current matching accuracy of 3% between strings.

Key electrical specifications include an input voltage range of 8V to 30V and an adjustable output voltage up to 60V. The device can deliver a maximum of 70 mA for each LED string. It supports PWM dimming with a ratio of 5000:1 at 200 Hz, providing precise brightness control. The switching frequency can be adjusted up to 800 kHz.

For enhanced reliability and protection, the TPS61199 incorporates MOSFET overcurrent protection, programmable LED short protection, adjustable LED open protection, and thermal shutdown protection. It is available in 20-pin SO and TSSOP packages, both with PowerPAD™ technology for improved thermal performance.

Applications for the TPS61199 include monitor LCD backlighting, LCD TV backlighting, and general LED lighting.
