TPS60231RGTRG4 Description

Short technical summary and product information.

The Texas Instruments TPS60231RGTRG4 is a versatile 3-channel, current-regulated charge pump designed for white LED backlight applications. It operates with an input voltage range of 2.7V to 6.5V and provides a regulated output current of 25mA per channel, with excellent 0.4% matching.

 

This device features multiple dimming options including Analog Dimming, Analog/PWM mixed dimming, and Direct PWM Dimming, allowing for flexible brightness control. The charge pump topology operates at a maximum switching frequency of 1250 kHz, contributing to high efficiency up to 90% and fractional conversion modes (1x and 1.5x).

 

Key features include integrated switches, soft start to limit inrush current, load disconnect during shutdown, fault detection, and thermal shutdown protection. The TPS60231RGTRG4 is housed in an ultra-small 3mm x 3mm 16-VQFN package, making it suitable for space-constrained designs. Its operating temperature range is -40°C to 85°C.

 

Applications include white LED backlights for color displays in cellular phones, smartphones, PDAs, handheld PCs, digital cameras, and camcorders, as well as keypad backlights.
