The Texas Instruments TPS60231RGTT is a 3-channel, current-regulated charge pump IC specifically designed for white LED backlight applications in devices such as cellular phones, smartphones, PDAs, and digital cameras. It features a regulated output current with 0.4% matching, driving up to 3 LEDs at 25 mA each.
This device supports various dimming methods including Analog Dimming, Analog/PWM mixed dimming, and Direct PWM Dimming, allowing for flexible brightness control. It operates with an input voltage range from 2.7V to 6.5V and boasts a high peak efficiency of 90%. The switching frequency is up to 1250 kHz, with a topology based on a switched capacitor (charge pump).
Key features include an integrated switch, soft start to limit inrush current, load disconnect during shutdown, and fault detection. The TPS60231RGTT is housed in an ultra-small 3mm x 3mm 16-VQFN package, suitable for space-constrained designs. It operates within an ambient temperature range of -40°C to 85°C.
