KTD2151EUO-TR Description

Short technical summary and product information.

The KTD2151EUO-TR is a programmable dual output LCD bias regulator designed for powering LCD displays. It integrates a boost converter and an inverting charge pump to generate positive and negative output voltages from a single input supply. The input voltage range is 2.7V to 5.5V, making it suitable for battery-powered applications. The positive output can be programmed from +4.0V to +6.3V in 100mV steps, and the negative output from -4.0V to -6.3V in 100mV steps. Output voltage accuracy is 1.0%.

The regulator delivers up to 80mA of output current with efficiency above 85%. It operates at a high switching frequency of 1.8MHz, allowing the use of small external components. The shutdown supply current is only 1µA, enabling low power consumption in standby modes. The device is available in two surface-mount packages: WLCSP-15 and TDFN-14. The operating temperature range is -40°C to +85°C.

Typical applications include LCD bias supplies for mobile phones, tablets, and other portable devices requiring both positive and negative voltages. The programmable output allows flexibility for different display panel requirements. The high efficiency and small package size make it suitable for space-constrained designs.
