The Texas Instruments TPS92390RHBR is an active LED driver controller IC designed for high-performance lighting applications. It operates within an input voltage range of 3 V to 48 V and provides four high-precision current sinks, each capable of delivering up to 200 mA DC current.
This device supports multiple dimming methods, including Analog, PWM, and a mixed Analog/PWM approach, with a high dimming ratio of 32,000:1 and up to 16-bit resolution. The switching frequency is adjustable from 100 kHz to 2.2 MHz, with features like spread spectrum for reduced EMI and sync input for external clocking.
Packaged in a 32-VQFN (5x5 mm) surface-mount form factor, the TPS92390RHBR is suitable for applications requiring precise LED current control and high-quality dimming. It includes features such as adjustable switch frequency, fault detection, I2C control, OVP, and thermal shutdown for robust operation.
Key electrical characteristics include a 3V to 48V input voltage range, 0V to 48V output voltage capability, and 200mA LED current per channel. The topology supports Boost and SEPIC configurations, making it adaptable to various power management needs in LED lighting systems.
