The ADP3041 TFT LCD Panel Power Module is a fixed frequency, PWM step-up dc-to-dc switching regulator with five buffers capable of 12 V boosted output voltage in a TSSOP 20-lead package. It provides high efficiency, low noise operation, and excellent dynamic response, and is easy to use. The high switching frequency allows for small, cost-saving, external components.
The ADP3041 is a fully integrated 1.5 A power switch and fixed frequency, PWM step-up dc-to-dc switching regulator designed for TFT LCD bias supplies. It features a 600 kHz oscillator frequency, allowing for the use of small inductors and MLC capacitors to save cost and board space.
The device includes five buffers capable of delivering 35 mA output current each with rail-to-rail input and output capability. Operating from an input voltage range of 2.5 V to 5.5 V, the ADP3041 can generate boosted output voltages up to 12 V while maintaining high efficiency (up to 90%) and low quiescent supply current.
