THV3058 is a controller IC for multi-channel power supply system with 3 channel PWM DC/DC converters(CH-1 Boost/CH-2, CH-3 Buck) and 2 channel charge pump circuits. THV3058 contains internal soft start, under voltage protection, over voltage protection and over current protection, which helps reducing the number of external component count and increasing reliability. Built-in positive and negative charge pump circuits(VGL/VGH) achieve enhanced performance.Ceramic capacitors are available for output, that provides space-saving and low cost system.THV3058 is ideal for TFT-LCD bias power supply system.
