The TPS60230RGTT from Texas Instruments is a versatile 5-channel charge pump IC optimized for white LED backlight applications in devices such as cellular phones and digital cameras. It provides a regulated output current with 0.3% matching over temperature, driving up to 5 LEDs at 25 mA each.
This device offers high efficiency through fractional conversion with 1x and 1.5x modes, and operates at a 1 MHz switching frequency. The input voltage range is from 2.7 V to 6.5 V. Brightness control is achieved through a PWM control signal. It includes internal soft-start to limit inrush current, low input ripple, and low EMI. Protection features include overcurrent and overtemperature protection, as well as undervoltage lockout with hysteresis.
The TPS60230RGTT is housed in an ultra-small 3mm x 3mm QFN package, making it suitable for space-constrained designs. It is designed for surface mount applications and operates within a temperature range of -40°C to 85°C.
Key features include regulated output current, PWM brightness control, high efficiency, and a compact package. It is suitable for applications requiring precise LED current regulation and dimming capabilities.
